The 36 little laser-cut 3" tall gray bears in each set (a by-product of our popular Bear Hugs sets) had been hand-painted with koala faces, and each had a colorful number on its chest. There were 6 sets of each number from 1 to 6, each number with its own color. Only a limited number of 85 sets were made. Of course, we do have our original Bear Hugs and Bear Hugs Jr. available without limit.

We have a few archival sets while they last, a once-in-a-lifetime offering,   $35

Acknowledgments — Notwithstanding the plentitude of gray bears that we had stockpiled as "free" raw material to use up, the Sudo-Koalas were arguably our most expensive IPP puzzle to date and a huge team effort. The heroic contributions of all are deeply appreciated. Thanks, guys!
