Hazmat the goofy little midget Ahrooo Little beefcake Shamoo swimming, Arnold thinking seriously but punking out about swimming, Hazmat running in circles like a mini malinois... Arnold likes to rescue toys from the pool if he can reach them from the edge and run them to the far side of the yard. He's a funny looking gremlin He was obsessed with trying to get to Shamoo He fell in twice and got in on his own twice, all four times he had to be rescued, he wasn't thinking straight about getting to the steps and he's sure not built for buoyancy. lol Best. Dog. Ever.
