I will say LadybugMom that when my son was little(3 or 4) he would throw temper tantrums over losing on a game or being asked to stop playing. He loved them so much that they became great currency in changing behavior starting with the issue of self-control. If he lost control at the game or when asked to stop he would lose his game privileges for the rest of the day or for longer depending on the behavior. He has long since learned to walk away from a game when he is getting too worked up and when told to turn it off I am often greeted with requests to "finish this battle and then turn it off". He only gets really bad if I let him play more than an hour or so.
As for SpongeBob, I kinda like him although I pretend otherwise. Shhhhhhhhhhhhhhhhhh........
