Treasure Chasers is a lego pirate variant of Cheese Chasers. It plays with the same rules as Cheese Chasers. There are pirates (mice), treasure (cheese), skeleton pirates (cats), and hms navy marines (mouse traps). The skeleton pirates have a special marking to make them easily distinguishable from the pirates. Multi-player is an option because there are four types of pirates (you choose which two will be a team).
