1) Tickle Me ELMO Surprise (2000) is by Fisher Price.  He measures 13 inches long and powered by 3 AA batteries installed in a compartment in his back via Phillips screwdriver (batteries and screwdriver not included).  Elmo has 5 ticklish spots:  under both arms, under both feet and his tummy.  One ticklish spot makes Elmo shake and laugh hysterically.  Each time you tickle him, his most ticklish spot changes location!  Watch video demo for entertaining laughter.  Imperfections include his fraying cloth tag and a small black mark (not crack) behind his right eyeball. 

2) The Ford BIG BIRD (1996) is by Tyco but Sesame Street teamed up with Ford to promote car safety, so he is wearing a removable shirt reminding kids to buckle up!  He measures 12 inches long (including the string hairs on the top of his head) and powered by 2 AA batteries installed in a removable compartment in his back via Phillips screwdriver (again, batteries and screwdriver not included).  Like Elmo, Big Bird also laughs and shakes uncontrollably when tickled at the right spots.  Big Bird still has his paper tag, but his beak shows a little dust on the tip. 

3) KERMIT THE FROG (undated) is by Nanco.  Still tagged with his paper "Jim Henson's Muppets" tag, Kermit is very versatile because his arms and legs are flexible enough to be posed in a standing (up to 19 inches long), sitting, cross-legged, arms akimbo, or just about any other position!  Includes a decorative orange loop on the back of his neck for hanging.

4) ERNIE (1997) is a combination plush and beanbag by Tyco.  He measures 9 inches long (including his puffy hair).  His coloration is a bit darker with normal wear, and his cloth tag is fraying.
