It's a cannon... What else is there? Long Tom is meant to be a cannon in shape and colourings of a white tiger. However some episodes have it black or even gold! Could be the fault of lazy animators or they just don't give a damn.
It serves as the ship's main cannon. Billy Jukes is seen to be cleaning the cannon, being a lazy ass and sleeping on it or cramming cannon balls down its throat.
- Billy's favourite thing in the whole wide universe!
- The name "Long Tom" could be a reference to the 155 mm Long Tom, which is a very badass-looking gun! It isn't a tiger though.
- Long Tom's colour schemes seem to flux between episodes. This is an animation flub. Long Tom's colourings flux from being a white tiger cannon, a reverse tiger, a gold
hippotiger or a plain looking tiger.
- Long Tom does not like Frosted Flakes, nor does he know Tony the Tiger.
- He may know Tigatron, though.
