A) When the Griffs go out and spend a day at the beach, Stanley forgets to put on sunscreen, and eventually gets sunburned, and turns red (like a lobster). Since he can't go back in the sun, he stays under a beach umbrella, and he and Dennis learn about lobsters. B) Dad and Lionel are building a bookcase together, and Stanley wants to help. Unfortunately, he's too little to use any of the tools his dad and Lionel are using. So he looks in the Great Big Book of Everything, and hopes to learn about carpentry from a Sawfish and a Hammerhead Shark.
