re: The Peanut Gang.
LOL
There was a Peanut series of CD rom games for tots when mine were little that were wonderful! I gave them away to friends though and can't find them now. There's two new ones out there now made by a different company that seems to be keeping the 'integrity' of the characters too, Snoopy: Where's that blanket, Charlie Brown? and Snoopy's Campfire Stories.
The Big Bear in The Big Blue House is probably the best thing out there right now along with Blues Clues and yes, Arthur.
Even Dexter has his own CD game now. LOL
Keep an eye on the mouse, they have a tendency to fall apart after a while. Try a track ball. *g*
