Got this from MousePlanet:
I'm a resort Cast Member (prefer to stay anonymous) and I'm passing this message on from a co-CM friend of mine who's a 'well weathered' character host and knows what happened.
"This event happened last yearthat Pluto is no longer working with us. The kid being chased was rough-housing with Pluto before the camera rolled, and he did not kick Pluto at all. Pluto gave chase, and the kid started to wildly run. Pluto ran as well, which is not allowed, so that's strike one. The kid being chased started to really get scared, and was screaming in earnest trying to get away. Pluto did not fully understand this. The woman who ran up and grabbed Pluto's arm was the child's mother. She demanded that he stop chasing her son, as it was no longer a game.
Pluto was angry that the woman had yanked his arm, and pulled back from her. That was strike twohe did not stop when a guest became in contact. He stepped off the curb and fell down. The woman did not push him, as he was already on the edge. However, he thought she had pushed him, and stood up with his paws in front of his face to show he was done. The guests in front of the camera were concerned, asking what happened, and Pluto pointed to the woman, "saying" she'd pushed him. The host then came over at this time to talk to the woman and find out the whole story. This Pluto was a very self-sufficient Pluto, who neither wanted nor needed a Host with him when he did his sets.
The falling down was strike three. However, the day in question was an exception. That Pluto decided to quit, citing that he was tired of the crowds and guests and stress it caused. The host in question was not at fault, as the host was told not to worry about Pluto and tended to the other characters. Pluto, however, took things too far on a hot day, with huge crowds, and a rowdy kid with a protective mom. The end."
