How do you get a cot on kindergarten game?

There's no standard kindergarten game called "Cot." There's no widely known children's game that specifically involves obtaining or using a cot as a game element. It's possible:

* You're misremembering the game's name: Try to recall other details about the game – what was it about? What did you do? Who played it? This might help identify the actual game.

* It's a very localized or homemade game: The game might be unique to a specific school, family, or group of friends.

* It's a misunderstanding: Perhaps "cot" is being used metaphorically within the game, or it's a completely different word that sounds similar.

If you can provide more details about the game, I might be able to help you figure out what it is.
