"Orangutangled" - Sudipta Bardhan-Quallen

First, please forgive the "monkeys" tag for orangutans, I figure it's close enough.

Second, Fun! This has bright, bold illustrations, great rhyme scheme, fun story (made me want to eat mangoes) and is full of silly animals and words.

Jan Thomas'... Yeah, anything written/illustrated by Jan Thomas. Similar illustrations and silly characters/story.

For the new reader, Carole Lexa Schaefer's "Monkey and Elephant" is a good series.
