Can you make up an (existent or non-existent) animal and one of its strange behaviorisms?

It is all just for some fun.
A supermarket here has this annual campaign where the kids get little toys, stickers or photos to collect (provided that their parents first buy groceries for an X amount).
This year it is animal cards which sport a photo and some Did you know that…? facts.
Some facts are weird.
Which made me come up with this question.

Did you know that the Sumatran flying bush frog, after mating, eats its mother in law?
