Tigger Onomatopoeia

In "Winnie the Pooh: Springtime with Roo," Tigger goes to have a word with Rabbit. What that word turns out to be may surprise you. ;-)

UPDATE: Someone commented to ask, "What is onomatopoeia?"
I'm having trouble getting my comment to post, so here's the answer: From Merriam-Webster Online Dictionary (m-w.com): "the naming of a thing or action by a vocal imitation of the sound associated with it (as buzz, hiss)." Also: "the use of words whose sound suggests the sense." So, an onomatopoeia is a word that sounds like the sound that it names.
