America's first Children's Poet Laureate, Jack Prelutsky's verse is wide-ranging and fun. There are 50 or so Prelutsky collections to choose from, but my daughter was extremely fond of this one when she was younger so it still holds a special place in my heart.
Beneath a blue umbrella
a melon seller sat,
selling yellow melons,
succulent and fat.
A huge and hungry hippo
made the melon seller mad
when he swallowed all the melons
that the melon seller had.
from Beneath a Blue Umbrella, rhymes by Jack Prelutsky; pictures by Garth Williams. Greenwillow, 1990.
If you haven't seen any of his collaborations with illustrator, Peter Sis, track them down. The Dragons Are Singing Tonight (1993), Monday's Troll (1996), The Gargoyle on the Roof (1999) and Scranimals (2002) are all published by Greenwillow.
