I think they should give Stampy 4 more tasks
1hr - Headbut other Elephants (requires Springfield Wildlife Preserve)
4hrs - Rescue citizens (requires Springfield Tar Pits)
6hrs - Fight the Ivory Dealer (requires Mr. Blackheart) (outdoor dual task)
8hrs - Eat peanuts (outdoor task)
And while they're at it, they need to give 5 tasks to the Capital City Goofball
