Toad enemy line

Toadonpa, the Poison Toad, and the Devil Frog are species of monsters found in Golden Sun and Golden Sun: The Lost Age. These monsters, resembling overgrown amphibians with elaborate body patterns, are palette swaps of each other and have differing levels of power and defense. The first two monsters, found in Golden Sun, are both unique boss-like monsters, while the Devil Frog in The Lost Age is a random monster specie.

Toadonpa
A giant-sized member with blue skin and red spikes. Toadonpa is an optional boss in Golden Sun, fought inside Lunpa Fortress at its cavernous basement as the climax of the Hammet sidequest; when Isaac's party with Ivan sneaks into the fortress and finds Master Hammet locked up, Lunpa's nefarious ruler, Dodonpa, happens upon them and throws a hidden switch, where a trap door opens up and Dodonpa's lumbering pet, whose name is an obvious play on its master's, attacks. As the battle progresses and nears its end, it becomes apparent to Dodonpa that Toadonpa is losing, so he tries to sneak up on the Adepts, but the beast is slain just then and falls on top of Dodonpa, hurting but not breaking his leg. In spite of being affronted by Dodonpa's dirty nature yet again, the party decides to move the amphibious corpse off him, then when Donpa appears he has Dodonpa locked up to atone for his misdeeds as Ivan's party escapes Lunpa with Hammet.

As a boss, Toadonpa is not among the most ferocious of enemies, though some of its stats are impressive. It features 2800 HP of which it regenerates 80 HP per turn, 266 Attack, 52 Defense, 82 Agility, and 18 Luck. It is extremely resistant to Mercury-based attacks, very resistant to Venus and Jupiter Psynergy, and extremely vulnerable to Mars attacks. Toadonpa can physically attack, use the monster skill Thrash to flatten an Adept for enhanced damage, cast Rotten Blood to lob yellow-green-violet slime at the target's feet and cause damage and lower the defense of a single Adept by 1/8, use Sticky Poison to lob green slime at a single Adept to cause damage and poison, and use Dark Blessing to breathe pink damaging breath and damage multiple Adepts and lower their defense ratings.

Toadonpa can easily fall victim to the rush-summoning tactic of summoning the four strongest summons in a row; by then Toadonpa would only have about 500 HP left, so the battle can end very quickly. So, fighting it at length may be recommended simply because it makes for a more interesting battle. Toadonpa, unlike most bosses, can fall victim to status ailments; inflicting poison upon it would cause it to accumulate massive damage on its own, over time, and if the Assassin's Blade is equipped on your party at that point, its One-Hit KO effect from its Unleash can conceivably work on the beast. Whatever the method, felling Toadonpa earns 999 EXP, 3200 coins, and a guaranteed Psy Crystal.

Poison Toad
A normal-sized member with orange skin and blue spikes. The Poison Toad is rather different from its blue peer even though it is fought in a pre-determined "boss" encounter, which is at the entrance to Floor 8 of Crossbone Isle and accompanied by two Thunder Lizards. It features 2250 HP without regeneration, 363 Attack, 97 Defense, 93 Agility, and 20 Luck. It is extremely resistant to Mercury-based attacks, very resistant to Venus and Jupiter Psynergy, and extremely vulnerable to Mars attacks.

The Poison Toad can physically attack, use the monster skill Rabid Fang to inflict heavy damage onto an Adept with red fangs and inflict Deadly Poison, cast Acid Blessing to breathe pink damaging breath and damage multiple Adepts and lower their defense ratings, and cast Rotten Blood to lob yellow-green-violet slime at the target's feet and cause damage and lower the defense of a single Adept by 1/8. With its ability to poison and lower defense while piling on the damage, the Poison Toad is quite a damaging opponent if fought at length, but like with all other Crossbone Isle subbosses having all party members use the four strongest summon spells in a row will easily dispatch the opposition by itself.

Felling the Poison Toad earns 1732 EXP, 2200 coins, and a guaranteed Water of Life. Taken together with the two Thunder Lizards, the EXP reward is raised up to 2576 and the coin reward 2642.

Devil Frog
A normal-sized member with pink skin and green spikes. The Devil Frog is very different from the two Toads from the previous game in that it is a common enemy, fought throughout Mars Lighthouse. It features 382 HP without regeneration, 347 Attack, 102 Defense, 173 Agility, and 15 Luck. It is extremely resistant to Mercury-based attacks, very resistant to Venus and Jupiter Psynergy, and extremely vulnerable to Mars attacks.

A Devil Frog can physically attack, use the monster skill Acid Breath (the same attack as Acid Blessing in the previous game, only renamed) to breathe pink damaging breath and damage multiple Adepts and lower their defense ratings, cast Rotten Blood to lob yellow-green-violet slime at the target's feet and cause damage and lower the defense of a single Adept by 1/8, and use Thrash to flatten an Adept for enhanced damage. It is not as powerful a common enemy as the others at Mars Lighthouse, such as the Aka Manah, Minos Warrior, and Fire Bird. Felling a Devil Frog earns 417 EXP, 248 coins, and an Elixer in uncommon cases.
