Snagglepuss was part of the Yogi Yahooies in the 1977 show Scooby's All-Star Laff-a-Lympics.

The answer is false because Snagglepuss was not part of the Yogi Yahooies in the 1977 show "Scooby's All-Star Laff-A-Lympics." Snagglepuss did appear in the Laff-A-Lympics series, but he was a member of another team called The Scooby Doobies, not the Yogi Yahooies. Snagglepuss was a pink mountain lion known for his catchphrase "Exit, stage left!" and he often participated in various Hanna-Barbera shows and crossovers, including Laff-A-Lympics.
