Snuffy and Big Bird want to play with their new friend- Marco, Gina's baby. They have brought a whole wagon full of things to play with, such as a baseball bat and glove, rollerskates, a pogo stick, and checkers. Gina tells them that the baby is still too young to play with any of those things. She suggests that they think like babies to come up with games that everyone can play together. Big Bird and Snuffy remember playing peek-a-boo, singing songs, and guessing animal sounds. They have so much fun on their playdate, but now they are ready to take naps. Snuffy and Big Bird can really think like babies, after all.
