Bird monsters

The Blue Bird is an enemy that only appeared in Thin Ice. It is a blue bird that moves around he ice, repetitively opening its mouth.

What is very dangerous about this enemy is that once a youth or adult version of the bird, falls into the water, a 2 smaller versions of the bird will pop out of the water. If an Adult Bird (left in picture) falls into the water, 2 Youth Birds (middle in picture) will pop out. If a Youth Bird falls into the water, 2 Baby Birds will pop out.

Baby Birds (right in picture) will simply die when they touch the water, and reproduce nothing. Adult Blue Birds and are hardest to trap due to them stopping if a hole is in front of them, thus, a hole has to be made around them, which is hard due to their speed.

The 2 younger versions are easier to trap becuase of their slowness. It is hard to trap large groups of Blue Birds because it can take a long time to trap the Adult Birds, which can leave very little time for the other birds.
