This was really funny! It was so impressive how you kept this joke up for so long. The best part was seeing the block with boobs. We'll make anything sexual, right? That's the power of Rule 34. Even the joke at the end was great.
I personally thought this was better than the "Metroid" cartoon. They're both about video games. I think I actually heard this joke before. It was Stephen Colbert joking about making a movie based on Tetris. Well, this wasn't a movie, but an anime. The voices were great too.
