No, Spazzstick has never been tested on animals. The only animals in the area are Arctic Fox, Caribou, and Polar Bears. We can't catch the Foxes, and putting lip balm on a Caribou is no picnic, so we don't even try. No one was willing to get close enough to a polar bear to put lip balm on it.
Except for Dwayne. He once tried to put lip balm on a Polar Bear. He said the Polar Bear looked like he had chapped lips. He also thought the Polar Bear wanted to be his friend.
We miss him. Not real smart, Dwayne, but he loved to hug stuff. Like Polar Bears.
