Udlikrop and Jiparolch are two dim-witted blue-skinned alien teenagers from the planet Plinus. They enjoy playing a card game called pickoggs that's as popular on Plinus as Pokemon is on Earth. They have few interests besides pickoggs and have difficulty explaining how the game works to people who aren't familiar with it. Udlikrop has a much smarter younger brother named Ip (real name Etarip) who was elected Vice King of the planet while being only the Plinusian equivalent to 8 years old.
