Several companies make Ice Cream Bubble Blowers. Tangent Toys and Oriental Trading Co. are two places they can be purchased.
Oriental Trading Co. offers several different colors of "ice cream" in the cone. Their items, which are about 4 inches tall sell for $7.20 for a dozen.
Tangent Toy Co. has ice cream cone bubble blowers with brown (chocolate) or red (strawberry) sauce. Unscrew the sauce to reveal that it is a lid and the ice cream cone is a bottle of bubbles. Use the large bubble wand connected to the bottom of the lid to blow lots and lots of bubbles.
