Being a children's mascot - as in, wearing a gigantic furry suit and the like - can be a pretty harrowing experience.
Not only is it ridiculously uncomfortable, but it can also be horrendously boring if you're stuck in one place and need something to occupy your mind. More to the point, if you have to repeat the same song or routine over and over again, that's going to drag you down even more.
So what do you do in situations such as this? You bring your own flavour to it - in this case, it's death-metal drumming. No, really.
This video, captured in a shopping mall in Japan, sees a children's mascot performing heavy metal-style drums over a well-known Japanese kids theme tune.
Amazingly, it actually works. Take a look.
