Rudy leads Muffin and Samuel on an expedition to the moon! They get astronaut outfits and Quinn gives them a rocket ship. But as they're about to take off, Mr Beakman explains to the kids that they can't possibly fly to the moon. The kids get Mr Beakman to come with them... to a papier-mâché moon Rudy has made in the tree!

Muffin spends a day with her daddy, who is the tree superintendent. While Mr Lovebird shows Muffin how he takes care of the tree, he will not allow her to actually help him. But when Mr Lovebird gets his wing stuck in a hole in a tree, Muffin is the only one small enough to save him!
