Wheeere's Wall-E?

Thought this was pretty cool.  Richard Sargent created this robot filled illustration.  From C-3PO to Bill and Ted bots to Jenny the Teenage Robot to Bender, they seem to be all here, but where's Wall-E?  -- It took me less than a minute to find him.  [I guess my speediness is a result of all the countless hours I took to look through various Where's Waldo? books as a child. lol]
