Yammy the Cat

Yammy the Cat was bag number 18 in McDonald's 2009 Teenie Beanie Babies promotion, one of the 30 toys McDonald's tied to the Happy Meal's 30th anniversary. The set ran from April 11 to May 15, 2009. Each toy came sealed in its own numbered bag, free with a Happy Meal, and in most restaurants was also sold on its own.

Each swing tag carried a code for online games and activities at happymeal.com or ty.com, the same kind of code Ty put on its full-size Beanie Babies 2.0 line. Yammy has no full-size Beanie Babies counterpart on record, which makes the Teenie its only physical form.
