	Stage 241	Dr. Toadette Dr. Luigi	The objective of this stage is to eliminate all viruses (32). This stage introduces ice fans. Making a match next to an ice fan will cause it to activate, and making another match while the ice fan is activated will freeze a random virus or certain objects. In this stage, viruses are grouped into four rings separated by Brick Blocks along with some ice fans in the middle column. The capsule amount is increased from 35 to 38 since version 2.0.0.
