Elmo will be at his ticklish best in a limited-edition “T.M.X. Elmo eXtra Special Edition due at retail Nov. 13. The plush from Fisher-Price Friends sports a gold badge to distinguish it from its predecessor, T.M.X. Elmo, yet has all the same features as well as new hidden silly surprises that can only be discovered when kids play, pose, and tickle Elmo in the right sequence. The key is to find the right combination of movements (raise his arm, tickle his belly, etc.) to activate the fun. T.M.X. Elmo eXtra Special Edition comes with one clue card featuring a rhyme to help find one surprise. Children and their parents can find the rest of Elmo’s silly surprises, through hints weekly between Nov. 19 and Dec. 17 at www.fisher.price.com. On Jan. 2, 2008, all of the correct sequences needed to unlock all of Elmo’s hidden surprises will be revealed on the Fisher-Price Web site. The plush retails for $39.99 and will be available only for 2007.
