Preschool PS2 Games, help me duders!

I need a ps2 game for the summer that would keep a pre-schooler, who can't read, occupied. Any suggestions?

Lego things. Lego Batman. Lego Star Wars. Disney's Cars, Meet The Robinsons, Toy Story 3, Kingdom Hearts, Harry Potter, Monster's Inc., Lilo and Stitch 626, Gran Turismo 3, The Nightmare Before Christmas Oogie Boogie's Revenge (Its $100 on Amazon, Ha!), Treasure Planet, Pirates of The Caribbean, Ratchet and Clank's everything, Jak and Daxter, Crash Bandicoot things, Spyro things, Rocket Power Beach Bandits, Bionicle, Up, Medal of Honor?., Bully, Rugrats Royal Ransom, Need for Speed Underground, Tony Hawk's Pro Skater 4, Sonic, Vice City., Dance Dance Revolution, Sing It, Kung Fu Panda, SSX, NFL 2K5, NBA 2K##, Madden, FIFA

First thing that comes to mind is Katamari Damacy or We Love Katamari. Those games have plenty of energetic audio-visual stimulation and lots of cute silly stuff going on that a young child might be receptive toward. The gameplay could be too difficult though.
