Geraldine and Kate's happy pants this week are dark blue, the kind of blue that makes them think of how it feels to jump into the pool for that first swim of summer.

Their happy pants pockets are full of all kinds of useful items this week - a piece of coiled wire, a rag, a spray bottle, a feather duster. It's time to give Happy Pants Headquarters a spring clean!

Along the way you'll hear music, a story about Lucy Lemon, learn some big words, and some fun facts about what it might be like to live in another part of the world...
