These are the pools and you need a certain amount of Nibbley Pibbleys to open the door in each of them:

• 13 Points
• 20 Points
• 20 Points
• 20 Points

PLAYER 1 - Red snake: Blue counts as 1 point, Red are 2 points, and Yellow are 3 Points.
PLAYER 2 - Blue snake: Blue counts as 2 points, Red are 1 point, and Yellow are 3 Points.

Ideally you want to end the level with 7300 Points total to not loose time on the counter after the stage.

In this level you can carry over points to the next pool:

• Example 1: If you have 12 points on your tail in the first pool and you eat a yellow to make it 15 points total, you carry over 2 points to the next pool, meaning you will only have to collect 18 points instead of 20. This works in every pool, so that every excess points will be carried over to the next.

• Example 2: This is very rare to get because it also depends on RNG spawns. If you have a door open and you eat a yellow Nibblefish going out the door making Rattle spit out the fins as you're going into the next pool you will start that pool with +4 points.
