15 Stunning Facts About 2016’s Biggest Movies

Grumpy-but-loveable octopus Hank's most distinguishing feature is that he's missing a tentacle, making him a "septopus" rather than an actual octopus.

This seems like a regular character affectation, right? Well, the real reason for Hank's disability is that two animation teams worked separately on his body and his limbs, and when combining the two it soon became clear that his body couldn't accommodate eight tentacles.

As a result, one of the tentacles was ditched and it was worked into the character's troubled back story. You can basically consider this one a happy accident, as it actually added to Hank's development and likeability.
