It’s a Mystery, Charlie Brown opens with this adorable five minute Woodstock sequence. He builds a new nest, then goes and takes a swim in a bird bath. A storm comes in–whatever its faults, Mystery does have some rather ambitious animation for a “Charlie Brown” special–the tranquil clouds changing into storm clouds looks awesome. Woodstock then has to survive on the water until Snoopy can save him. Once Snoopy comes in, things start to get less adorable. Mystery starts going for gags, because whenever Snoopy tries to help Woodstock, something goes wrong because of Snoopy’s callousness. For a while it seems like a subplot is going to be Woodstock snapping.
But it’s not. Because Mystery doesn’t have any subplots.
Once the storm is over and Woodstock is dry, Snoopy walks him home. Only the new nest is gone, so Snoopy dons a Sherlock Holmes outfit and they get investigating.
Wait, did I forget to mention Sally (Lynn Mortensen) has a science project due and the subject is nature. She needs something from nature.
So Snoopy and Woodstock investigate the Peanuts kids, starting with Charlie Brown (Todd Barbee) under a hot lamp. Then Lucy and Linus, then Marcie, then Pigpen, then Peppermint Patty. None of the scenes stand out except the Peppermint Patty one, where Patty decides Snoopy is playing cops and robbers and plays as the robber and attacks him. It might be a good scene if Donna Le Tourneau’s voice work on Patty were better. There’s got to be something special in the voice of a character who thinks a bipedal dog in a costume is a funny-looking kid and Le Tourneau doesn’t have it here.
After all the investigating, they go to the school and find the bird nest. Even though they’re just following the footprints from the tree, which Mystery previously implied led to Charlie Brown’s house and maybe the plot would move along a little faster. The trip to the other kids’ houses is narratively pointless. Other than to keep doing this sight gag where Snoopy’s bubble pipe makes a big bubble. The big bubble always pops on Woodstock, soaking him once again. Given Woodstock almost drown to death in the opening scene, it’s a little mean. Mystery is a little mean to Woodstock, who’s basically the only not annoying character in it.
Because Sally gets really, really, really annoying. Mortensen plays her a little sociopathic, which is funny, but she’s fighting with Woodstock, who’s sympathetic.
The last third is a series of unfunny jokes. Mystery goes out on a particularly bad one.
It took six guys to come up with the story for Mystery–Charles M. Schulz isn’t credited with them, though he wrote the teleplay. They didn’t come up with much. For a while it seemed like it’d be focused more on Snoopy and Woodstock, so dialogue-free comedy. But no.
It’s not terrible, it’s just not successful. It doesn’t really try to succeed either. It’s also not assured enough to be rote.
