Rick in “Unfinished Business”

It's rainin' cats and dogs, but I never thought an egg would rain on me' 'ead! Look, mate, that egg of yours won't hatch if you don't protect it from the cold and rain. Here's a trick a platypus taught me. [surrounds the Galbo egg with a ring of grass and provides Kirby with a leaf to shield it with] That'll shelter the shell from the rain, but you're going to have to help the little fella stay cozy. Just like this. [incubates the egg for a second] Now, you try. [Kirby incubates the egg] Righto! Good luck, Kirby!
