Danger is one of three pets living on Horton's lot, located in my MSR01 neighborhood. It's partially due to him that I was able to unlock more of the unlockables for the pets in the game.
Danger's aggressiveness gets him into lots of fights with Tiffany, a stray who loves to visit the lot; Danger also loves to torment Snoop, the resident parrot. :P
OT note: Whenever I'm not on LJ, or whenever LJ is down, I can usually be found hanging out here:
