Go to the cellar!!
From the Super Mario Wiki, the Mario encyclopedia
Go to the cellar!! is an alternative version of Wario Land II's second chapter. It can be accessed from stage 1-5 and can be seen as an alternative path, since it skips regular chapter 2 and reconnects with chapter 3 afterwards.
Wario's quest has not been delayed by a battle with the giant snake, so he is able to catch up with the intruders that have stolen his treasure and follow them to a system of underground tunnels. The chapter is composed of various cavern-themed levels and an underground rail road track. At the end, a battle with the cave master awaits.
