It is time to hit the beach for the most unusual celebration of the summer. You will join a massive gathering of joyful hippopotamuses who are completely obsessed with their belly buttons. From tiny baby hippos to massive singing adults, everyone is proudly showing off their midriffs and joining in the boisterous chorus. The incredibly catchy rhymes and hilarious illustrations capture the absolute silliness of a beach party dedicated to navels. You will find yourself laughing out loud at the absurdity of the situation and the unbridled confidence of the characters. It is a wonderfully weird and wonderfully charming tribute to a part of the body that rarely gets its own song.
