Archeotoad is an enemy in Final Fantasy V. While weak, its Pond's Chorus, which inflicts Toad to the party, is troublesome. The best way to defeat them is to exploit their Ice weakness. Hi-Potions can be stolen from them.
The word root archaeo-, as in "archaeology," comes from Greek archaios meaning "ancient."
Its name therefore simply means "ancient toad," fitting for a creature found in the ruins.
