In response to Uncle Scott's Question:
On the show Oscar has a pet worm and a pet elephant (you never see the elephant, he stays in the can). You can't see a 1/25th scale worm, and an elephant would require more suspension upgrades than I was willing to do, so I went with a pig. I'm thinking that a pig and Oscar would have a lot of common interests and so far they seem to be getting along fine. Well, as well as a grouch gets along with anybody.
