Rock-O-Jello

From Teleram Wiki

Rocko's favorite pony.

Rock-O-Jello is quite the joker, but also a good friend.

Rocko appears as a character in Teleram: The Series, voiced by Samuel Vincent. He first appears in "Super Teleram", in which he dares Teleram and Doctor Bugs to drink an unknown liquid, which turns them into super heroes. But the episode turns out to be a dream.
