5. Broken Block and the long one like just pass through that small gap lmao!
6. Floating Blocks leading to Game Over XD
7. Puyo Puyo?
8. Mario? XD Well, kinda....
9. Very weird blocks representing rooms. (SPOILER WARNING: When watching this, make sure you're not drinking or eating anything or you'll choke to laughter) The one playing Tetris said "Why are there so many toilets?" and each room has their own prices. At the end of the vid, he said "I don't want this house! It's so expensive and it has so much toilets in it!" The caption said also the house would cost him 60,000 Yen or $500 in the us. XDXDXDXD I came and cum so HARD watching it! DAMN IT!

It's really funny and it's a good anti-depressant. :D
