Human-sized hamster balls

The "" are, as the name indicates, hamster balls that have been made big enough to hold a human inside.

History
While Mabel and Dipper were eating breakfast, Dipper read a Wacky Newz periodical and showed it to Mabel. However, the girl instantly spot the hamster ball and remarked that she was human sized in amazement.

She daydreamed about it, where she proudly showed it off to another hamster and then left the house, where a pair of teenagers saw her and remarked in amazement as she left.

She then daydreamed about it again when they were faced with the decision of staying with their Grunkle Stan in his Stanowar or go with Soos in his S.S. Cool Dude to find the Gobblewonker.

This time, she interrupted Dipper in the middle of an interview with Charlie, where she complained that she wasn't getting an interview as well before chasing Dipper and the tv host.

The ball made another appearance during Mabel, Dipper and Soos's battle against an enraged Bill Cipher in the Stan-shaped dream arena. The trio summoned it to block the dream demon's nightmare ray.

Appearance
The object is pretty much what its name says; a hamster ball that is human sized. The only variation seen in the series is colored pink.
