Disney had a lot of fun with the difference in size between Mr. Big and his Bodyguards. And, knowing he has complete loyalty from the polar bears, I can imagine him occasionally using his size to mess with them from time to time. Not too often. Just every once in a while, when the old mobster needs a laugh.
Thanks to あさやみのる (Asayaminoru) for this fun little comic, thanks to LMAbacus for translating it into english for us, and thanks to gfcwfzkm for editing it. You can find the original on pixiv and, as usual, read from right to left and get your translated comic after the break!
