	Stage 601	Dr. Larry Dr. Peach	The objective of this stage is to eliminate all viruses and collect all keys. In this stage, colorful crates form three intersecting circles with like-colored viruses within the respective crates, with red viruses taking priority. One of the keys is in one of the intersecting areas while the others are outside the circles.
	Stage 602	Dr. Dolphin Dr. Bowser Jr.	The objective of this stage is to collect all purple coins. In this stage, bubbles are arranged in a wave, with purple coins and an exploder in the highest point of each column and viruses in the others. Caged crates and flasks are located above the bubbles, and the area above them are purple coins, exploders and shells. The filled flasks in this stage will shoot out bubbles containing viruses.
	Stage 603	Dr. Daisy Dr. Fire Peach	The objective of this stage is to eliminate all viruses and destroy all crates. In this stage, groups of two caged crates in a column are arranged in a checkered pattern with floatie viruses and exploders in between, split into two groups in the middle. The respective lock blocks are located in the corners in the topmost row.
	Stage 604	Dr. Bowser Jr. Dr. Luma	The objective of this stage is to eliminate all viruses and destroy all barriers. In this stage, the even-numbered columns contain bubbles containing viruses and inactive barriers, while the odd-numbered columns contain bubble machines and Empty Blocks. Additional viruses are found in the middle seven columns. Prior to version 2.0.0, the stage layout was different. The following changes were made: The five bubble machines in the ninth row are removed.
	Stage 605	Dr. Waluigi Dr. Toad	The objective of this stage is to eliminate all viruses and collect all keys. In this stage, the keys and doors are either found inside barrels or are covered in dust clouds (the other dust clouds are dust viruses). The leftmost and rightmost columns have light-blue cages with its corresponding lock block in the second column, while the third and seventh columns have green cages with its corresponding lock block in the middle of the topmost row. Ice fans are located in the middle five columns in a "V" pattern.
	Stage 606	Dr. Larry Dr. Wendy	The objective of this stage is to eliminate all viruses and collect all coins from Coin Blocks. In this stage, there is a ring of Brick Blocks (all containing coins) with lock blocks inside. both the left and right of this ring are colorful crates in a checkered pattern with viruses on the outside. The left group has caged floatie viruses and the right group has shells in the same row as the lock blocks.
	Stage 607	Dr. Fire Peach Dr. Baby Daisy	The objective of this stage is to collect all virus coins.
