More than 500,000 units of this toy have been sold, and Booger Buddies are still considered one of the most popular items at Esco Imports, the company told TDmonthly. Designed exclusively for Esco Imports, Booger Buddies consists of green slime jelly encased in a soft plastic face. When the figure’s cheeks are squeezed, green slime oozes out of the nose area. When the face is released, the jelly retreats back into the toy. Unlike other slime toys, this one can easily be carried around on the included keychain without any worry about messy pockets or bookbags. It comes 24 pieces per box.
