As with A Boy Named Charlie Brown (1969), the Peanuts characters get onscreen credit in the opening credits, with Snoopy getting top-billing.
At the end, just as an annoyed Charlie Brown exits stage left, Snoopy and Woodstock are still on top of Snoopy's doghouse, with Woodstock typing the closing credits (which appear over/around the two in typewriter text) on Snoopy's typewriter and Snoopy "dictating" the credits to him. In a similar manner to A Boy Named Charlie Brown (1969), as Woodstock types the credits, the film's crew members, corresponding to the names in the credits, appear in groups in the background.
