In the original release, horny toads were fought by Ratchet both during "Investigate crash site" and "Save Ratchet's planet". In the re-imagined release, horny toads were fought during "Head to the fairgrounds", but not during "Return to the garage" at night, where only blarg enemies appear.
Horny toads are orange, toad-like creatures that bounce on their two back legs to move in a hopping fashion. Though bipedal in movement, with two large back legs, they have two smaller front legs used for balance. Horny toads have orange skin, with white spikes and dark brown strikes across their back, matching the arid planet's surface.
In the 2016 re-imagined release, horny toads instead have dark blue skin rather than orange on their back, but have peachy, yellow skin below. They also only appear during the daytime. When they spot Ratchet, they will react by making a croaking noise, and their eyes will widen. Horny toads are also much faster at jumping.
Horny toads attack in numbers, using their agility to their advantage. Their large jaw produces a melee range offensive bite, their only attack, which is signified by them pausing from moving to face the player, followed by bellowing a loud croak and bite. They have very little defense, and they can be easily defeated with a single strike from the OmniWrench, which can be turned into a multi-strike against multiples of them. Other weapons can also be effective at clearing out large groups encountered upon returning to Veldin.
