NSI International Inc. expands its Wubble Ball line with Wubble Fulla, a ball that is filled with either gooey slime or Magic Marbles.

Kids can choose from either Wubble Fulla Slime or Wubble Fulla Marbles. Wubble Fulla Slime is filled with slime, while Wubba Fulla Marbles is filled with Magic Marbles, which NSI defines as colorful and squishy round balls made of polymer that absorbs water. Both items are made for kids ages 6 and up.

A combo set is currently available at WubbleBall.com, which includes one of each Wubba Fulla. The balls are coming soon to Target, Toys “R” Us, and Walgreens.
