Aliquippa - some sort of iguana or gecko-like creature, clinging to the wall. It uses its sticky tongue to snare prey, including your party.
Shamokin - a humanoid sitting near an extinguished bonfire. The smoke rising from the flames twists and forms the shape of the monster you have to fight
Kammerer - a palette-swap of the implike Hammerers you ran into earlier in the game. These hit harder and cause Confuse when they strike with their oversized mallets.
Netcong - a gorilla retiarus. Tries to cause Stop or Paralyze status with its net before stabbing with the trident.
Ashtabula - the little shadowy creature uses fire spells, then hides behind the giant rune-engraved stone slab it learned the fire spells off of
Ney - a small fairy horse. Constantly uses Sleep status, has ridiculously high Evade, and reflects spells.
Minonk - a tiny martial artist.
Streator - when the roads themselves grow giant rocky fanged maws and try to devour your party it might be time to reconsider their career choices
Broadnax - a sweaty barbarian dual-wielding, as you may have guessed, a broadsword and an axe.
Bunnlevel - if you can defeat this lagomorph before it runs away it's worth a lot of EXP.
Cooleemee - attacks with its magic, but if you hit it with an ice spell, it will instead cast a healing spell on your party and flee the battle.
Batman - contrary to expectations this is a cameo appearance of the player character from OFF
