Peanut Butter and Jellyfish, or P.B. Jellyfish, are jellyfish-based Foodimals that have peanut butter and jelly sandwiches for heads and long stringy limbs that are also made out of peanut butter and jelly. They were first spotted by Earl when they were going down a river in the Foodimal Jungle and described them as "tasty-looking jellyfish".
