It's possible that:
* "Shenanigans" is a homemade game: If it's a game created by a group of friends or family, there wouldn't be a set release date.
* You're thinking of a different game: There might be a board game with a similar name or theme that you're remembering. Could you provide any other details about the game?
* "Shenanigans" is a term used to describe a game: It's possible the term is used to describe a type of game with a lot of chaotic fun.
To help me find the right game, can you tell me more about it? For example:
* What are the main game mechanics? (dice rolling, card playing, etc.)
* What is the general theme? (party, strategy, etc.)
* Do you remember any specific details about the game? (artwork, characters, etc.)
With more information, I can hopefully help you find the game you're looking for!
