Last year, T.M.X. Elmo proved that laughter is contagious, and now Elmo's friends Ernie and Cookie Monster join in the riotous fun! Both 11-inch plush dolls put their own spin on the exciting action of the original T.M.X. Elmo. Ernie giggles and laughs as he kicks his legs, spins in a complete 360-degree circle, and gets back up. Kids simply tickle Ernie's belly to get the laughter started. Cookie Monster sold separately.
