Apparently Hippo was very good this year. The Three Kings and other humans showered gifts upon him. Just opening them all was exhausting.
In addition to the festive sombrero he received early, Hippo also got a warm knit sweater to keep him toasty through the winter. In the spring he can play with his new baseball bat, ball, and glove.
He also has his very own little hippo-sized game of Hungry Hungry Hippos. There's a book about another young hippo who was adopted by an old, old tortoise. And Hippo has a travel-sized tiny hippo playmate, Smiley.
