Toadonpa, the Poison Toad, and the Devil Frog are enemies that are battled in Golden Sun and Golden Sun: The Lost Age. These monsters, resembling overgrown amphibians with elaborate body patterns, are palette swaps of each other that have differing levels of power and defense and are fought in different locations in the games. The first two monsters, exclusive to Golden Sun, are both unique boss-like monsters, while the Devil Frog exclusive to The Lost Age is a randomly encountered common enemy.

In Golden Sun and Golden Sun: The Lost Age

Toadonpa

Toadonpa (ゲロンパ Geronpa) is a giant-sized level 27 variant with blue skin and red spikes. In Golden Sun, it is a boss encounter that is fought at the end of the optional dungeon Lunpa Fortress, in a scripted event and cutscene that occurs upon opening up the cell door at the deepest part of the dungeon.

Toadonpa can easily fall victim to the summon-rush tactic of having all Adepts summon the four strongest available summons in a row; by then, Toadonpa would probably have about 500 HP left, so the battle can end very quickly. In spite of its large amount of HP and how its HP regenerates, this may not be so difficult a battle to conduct normally. Toadonpa appears to be affected by status ailments relatively often; inflicting poison upon it would cause it to accumulate massive damage on its own, over time, and if the Assassin Blade is equipped on your party at that point, the One-Hit KO effect from its Unleash can conceivably work on the beast.

Toadonpa is especially likely to be affected by Delusion-inflicting and Sleep-inducing effects. Its statistics are as follows:

Name	HP	PP	Attack	Defense	Agility	Luck
Toadonpa	2800	0	266	52	82	19
Elemental Resistances and Levels			Exp	Coins	Item Dropped	Drop Rate
175 (Lv 4)   100 (Lv 2)   100 (Lv 2)   25 (Lv 0)			999	3200	Psy Crystal	1/1

Toadonpa regenerates 80 HP at the end of each turn.

Toadonpa uses the following battle commands with low intelligence:

Command	Chance to use	Elem. Stats used with *	Description
Dark Blessing	100/256 (39.1%)	85 Power Level 0	Enemy ability where the user generates a gaseous pink cloud at the party of Adepts. Deals a Mars-aligned attack with 170 base damage that is spread out across 3 enemies with low damage distribution, and each hit enemy has a chance to get their Defense rating temporarily lowered by 12.5%.
Thrash	76/256 (29.7%)	115 Power Level 4	Enemy ability where the user leaps up and comes crashing down on a single Adept, letting loose a burst of purple energy on impact. Deals a Mercury-aligned standard attack with 30 damage points added to the end result, and if this attack does not down the target, it has a chance to lower the target's HP down to 1.
Rotten Blood	46/256 (18%)	85 Power Level 0	Enemy ability that lobs a mound of multicolored fluid at a targeted Adept's position. Deals a Mars-aligned attack with 44 base damage, and it has a chance to temporarily lower the target's Defense rating by 25%.
Sticky Poison	23/256 (9%)	115 Power Level 4	Enemy ability that lobs a light green mound of slimy water onto a single Adept's position. Deals a Mercury-aligned attack with 16 base damage, and the target may be afflicted with Poison.
Attack	11/256 (4.3%)	--	Standard physical attack.

Poison Toad

The Poison Toad (ポイズントード) is a normal-sized level 34 variant with orange skin and blue spikes. In Golden Sun, only one is fought throughout the entire game, together with two Thunder Lizards as one scripted boss encounter that occurs on the eighth "dungeon floor" of the optional Crossbone Isle as soon as you try to enter the door to that floor's puzzle room.

Like with almost all other Crossbone Isle mini-boss encounters, having all party members use the four strongest summon spells in a row will easily dispatch this monster and the two normal monsters beside it easily. If you'd rather fight it at length, you should find that after removing the two Thunder Lizards, it by itself should be quite a manageable enemy, even though its most-used attack can cause the damaging Venom effect. Venom can always be easily removed by Cure Poison, and Wish Well is always extremely useful at weathering assaults and outlasting the opposition.

Poison Toad is especially likely to be affected by Delusion-inflicting and Sleep-inducing effects. Its statistics are as follows:

Name	HP	PP	Attack	Defense	Agility	Luck
Poison Toad	2250	0	363	97	93	20
Elemental Resistances and Levels			Exp	Coins	Item Dropped	Drop Rate
175 (Lv 4)   100 (Lv 2)   100 (Lv 2)   25 (Lv 0)			1732	2200	Water of Life	1/1

A Poison Toad uses the following battle commands with low intelligence:

Command	Chance to use	Elem. Stats used with *	Description
Rabid Fang	100/256 (39.1%)	95 Power Level 2	Enemy ability where a glowing red image of a pair of jaws chomps at the position of a targeted Adept once. Deals a Venus-aligned standard physical attack with 36 damage points added to the end result, and the hit Adept has a chance to be afflicted with Deadly Poison.
Acid Blessing	76/256 (29.7%)	85 Power Level 0	Enemy ability where the user generates a gaseous pink cloud at the party of Adepts. Deals a Mars-aligned attack with 190 base damage that is spread out across 3 enemies with low damage distribution, and each hit enemy has a chance to get their Defense rating temporarily lowered by 12.5%.
Attack	52/256 (20.3%)	--	Standard physical attack.
Rotten Blood	28/256 (10.9%)	85 Power Level 0	Enemy ability that lobs a mound of multicolored fluid at a targeted Adept's position. Deals a Mars-aligned attack with 44 base damage, and it has a chance to temporarily lower the target's Defense rating by 25%.

Devil Frog

A Devil Frog (デビルフロッグ) is a normal-sized level 35 variant with pink skin and green spikes. In stark contrast to the other two Toads from the previous game, this is a randomly fought monster in The Lost Age, fought throughout Mars Lighthouse.

The Devil Frog has more HP and offense than the Doodle Bug, but that is not saying very much. It is still quite an average monster in comparison to the likes of the Aka Manah and Fire Bird, and it is only very occasionally that it may lower an Adept's HP down to 1.

Although the Devil Frog does not appear in Golden Sun, it exists in the code of the game, but none of its statistics are coded beyond weak placeholder stats. Also, it only has a single question mark for a name.

A Devil Frog is especially likely to be affected by Delusion-inflicting and Sleep-inducing effects. Its statistics are as follows:

Name	HP	PP	Attack	Defense	Agility	Luck
Devil Frog	282	0	347	102	173	15
Elemental Resistances and Levels			Exp	Coins	Item Dropped	Drop Rate
175 (Lv 4)   100 (Lv 2)   100 (Lv 2)   25 (Lv 0)			417	248	Elixir	1/32

A Devil Frog uses the following battle commands with low intelligence:

Command	Chance to use	Elem. Stats used with *	Description
Attack	4/8 (50%)	--	Standard physical attack.
Rotten Blood	2/8 (25%)	85 Power Level 0	Enemy ability that lobs a mound of multicolored fluid at a targeted Adept's position. Deals a Mars-aligned attack with 44 base damage, and it has a chance to temporarily lower the target's Defense rating by 25%.
Thrash	1/8 (12.5%)	115 Power Level 4	Enemy ability where the user leaps up and comes crashing down on a single Adept, letting loose a burst of purple energy on impact. Deals a Mercury-aligned standard attack with 30 damage points added to the end result, and if this attack does not down the target, it has a chance to lower the target's HP down to 1.
Acid Breath	1/8 (12.5%)	85 Power Level 0	Enemy ability where the user generates a gaseous pink cloud at the party of Adepts. Deals a Mars-aligned attack with 190 base damage that is spread out across 3 enemies with low damage distribution, and each hit enemy has a chance to get their Defense rating temporarily lowered by 12.5%.

Story relevance

Spoiler warning: The following section(s) contain plot details that some people may not wish to learn before reaching this point in the game on their own.

When Isaac's party sneaks into Lunpa Fortress to look for and rescue the imprisoned Master Hammet, they eventually come to his cell and open his cell door, and Ivan and Hammet have their reunion. Just then, Lunpa's nefarious ruler, Dodonpa, comes in and taunts them, stating that keeping Hammet here is his awesome way of extorting money from Hammet's town of Kalay. He attempts to have the meddling Adepts crushed by throwing a hidden switch, and the wall opens up, from which Dodonpa's lumbering pet, Toadonpa (whose name is an obvious play on its master's), emerges and engages the Adepts in battle.

As the battle progresses and the Adepts gain the upper hand, it becomes apparent to Dodonpa that his monster is losing, so he attempts to sneak up on the Adepts from behind and attack them himself. But Toadonpa is slain, and its body falls straight onto Dodonpa, to the Adepts' surprise. After the Adepts learn from Hammet what he was trying to do, the Adepts decide, in spite of being affronted by Dodonpa and his dirty nature yet again, to move the monster's corpse off him, but its weight is heavy enough that all four of them must lift it off to the side together, and Dodonpa's revealed to have had his leg broken under the monster's weight. Following this, Dodonpa's father Donpa appears, and the Adepts agree with him to have Dodonpa locked up in the same cell for a while so that the ruler of thieves may atone for his misdeeds. Ivan's party escapes Lunpa with Hammet in the meantime.

Spoilers end here.Those who did not want the plot ruined for them may now continue reading as normal.
