Another one from PvZ wiki it is called Obstacle Course.

Rules:

1. Don’t do impossible obstacles like, a toxic pool with no thing else.

2. Don’t swearing.

3. No being immortal.

4. Don’t make any stupid replies like I do it, I do that.

2. Riddikulus. The next room is do nothing for 50 hours.

3. I ask someone to time travel with me in 50 hours later. The next room is claim your hill.

4. My hill. The next room is don’t talk about fight club.

And so on.
