Bob has the appearance of a regular squirrel. He's brown and has big eyes with dots in them.
Bob is playful and mischievous. He's friendly overall but he's shown to have a bit of dark side. For example, in "Sneezin' Season" he is fanatically laughing with the Glooms much to their surprise.
In the series
In the episode "Sneezin' Season", he appears in the Jolly Berry trees, playing with Dopey. He later spots the Glooms and crawls into Grim, eating his berries and gets sneezed away with the Glooms by Sneezy. For some reason he decides to join the Glooms as they attempt to get some of Grumpy's beard hair but gets sneezed away with them each time. When the Jolly Berry Pie Festival starts, he tags along with a kid-sized Hildy to get Grumpy's whiskers. The two, hidden in some pies, are unknowingly taken by Sneezy to Grumpy and as she clips off some hair, Sneezy sneezes her back to Grim while Bob jumps onto Grumpy. Doc then realizes that it's Bob that Sneezy is extremely allergic to, just as the Glooms prepare to make their conquering spell. Bob then helps Grumpy thwart the Glooms by making Sneezy sneeze a ton of pies onto them.
He and Dopey collected fireflies for most of the episode.
He went foraging with Dopey.
Bob made his appearance as a contractor, and he directed a group of beavers to chomp on wood as part of building a new bed for Queen Delightful.
