This is an exciting game that young children particularly would like playing, finding 'evidence' and 'searching' for hidden 'treasure', watching their friend's progress on their TV and allowing a special two-player co-op where they can play together to the very end!
It starts with Mario and Luigi running around looking for old stones around Toadstool Castle. And that's when they find a block of ice that had a cracked shell on the inside. Luigi thinks it is the fossil of an ancient being, and Mario thinks similar, so they decide to look for evidence on it... until Bowser Junior (very rudely) interrupts and nabs the fossil... and Daisy's brand-new crown she only just got.
