The bee resembles a stereotypical bee. The bee is yellow with black stripes. It has a black stinger and a black head, with no visible eyes. Like its name suggests, it is rather fat.
- Princess Bubblegum stated that the bee receives pollen from the flower. This is partially true as bees in real life get nectar and pollen from flowers.
- The Fat Bee and Jake are the only characters that die and are revived in the same episode.
