Boy 9 years old

Real name was Roger, but he doesn't remember. Can speak, but cannot read.

Red monster An obnoxious fellow

Won't mess with you if you don't mess with him.

His name was originally 'Toilet Monster', but that sucked, so he's officially called Red Bean.

Leaving detailed info just in case. Referenced Gwang-gi's work. My sincere apologies regarding this.

Clock monster. A sly character who picks fights.

A kind and gentle wooden signpost.

Genius

Fake Roger
