HUMOUR WARNING: this story is about boo-boos and poo-poos! It gets messy and funny! Follow Horatio Haha on his crazy, slightly disgusting adventures with Fifi the aye-aye. What's an aye-aye? Good question. An aye-aye is a rare type of freaky-looking lemur. So come to Madagascar, where this story is set, and revel in the wonky, wordy adventuring of Horatio Haha and the wee-wee of Fifi!
