I'VE LOST MY HIPPOPOTAMUS by Jack Prelutsky (Greenwillow 2012) is another welcome addition to the collection of Prelutsky's poetry books. Many of these poems involve some fun word play, a hallmark of Prelutsky. What teachers will love is the poems that include vocabulary that might not be familiar to readers but that is clearly "defined" in the context of the poem. Invented animals, skating potatoes: it is all here. One of my favorites in this new collection is about a snake that can do arithmetic; it is, of course, an adder. (Insert groan here). <196>
