Kawaii! Here we go again. The people of Japan continue to incapacitate us with their capacity for creating cuteness. In this short video, YouTube user heibonkinoko shows of the miniature house they created for their hamster.

But it’s not just a tiny house. That wouldn’t be cute enough, you see. This amazing little dwelling is called the “Hamster-only trick mansion” or “Ninja Mansion” because it’s full of secret doors and passages. Watch the video and you’ll watch the hamster discover all of these wonderful, hamster-sized secrets for himself.
