These are Bubble Buddies from the Tiny Toons Adventures cartoon series. I have eight of the blowers: Sweetie-Bird, Buster Bunny, Shirley the Loon, Elmyra Duff, Furrball, Dizzy Devil, Plucky Duck, and Hamton J. Pig. I suspect there are more since some of the major characters are missing.
The characters are soft plastic and marked "TM & c. 1994, Warner Bros., China." The bottles are marked on the bottom with "Dorda Toys. Made in China."
