Snoopy Come Home (1972)

Character mistake: During the monopoly game, Peppermint Patty rolls a 12 on the dice but only moves 7 squares.

Continuity mistake: When Clara is chasing Snoopy and Woodstock, she is holding a leash in her hand. When Clara is standing at the top of the stairs and sees Snoopy and Woodstock run past, the leash has disappeared, but when Clara slides down the banister, the leash is back in her hand again.

Continuity mistake: When Snoopy and Woodstock lie down after finishing their meal at the camp, you can see there is still food on both their plates, but in the next shot the food has disappeared.

Trivia: This film marked the on-screen debut of Woodstock.

Charlie Brown: Hmm, a letter to Snoopy. What a surprise. I never get any mail. I had 15 pen pals once, and they let me do all the writing.

Charlie Brown: If I don't find out what happened to Snoop, I think I'll go out of my mind.
Linus: If you'll calm down for a minute, Charlie Brown, I may able to conduct a little private investigation.
Charlie Brown: Just what I need, a blanket-carrying Sherlock Holmes.

Charlie Brown: You know what I need? I need more hellos.
