When these unsuspecting plush tsum tsum's fell from the sky mysteriously, he never expected to find one of the tsum's to look like him but in a nubby plush form: But he didn't necessarily mind it. He wanted to care for it, another thing he didn't expect? For his tsum to be quite clingy to you. Sure, you were his very close human friend whom he deeply cared about and who was also his technically first friend. Who wouldn't especially when you have been isolated from the outside world for while as a kid? He would, never admit it, but, he was a bit jealous of the tsum. He didn't really like that it was clinging onto you, I mean; you literally just walked up to it and it just squeaked happily and clinged onto you for dear life with it's nubby plush hands! You were a bit shocked, you didn't expect this at all, the other tsum's never did this to you, so, why was Malleus' tsum doing it now? But sadly, that would never be answered and probably would never get answered to your dismay.
