Game information

Thin Ice

Bird monsters are hard to kill enemies, due to there vast number to sink and the low time limit given to kill them all. There are three variations of bird monsters: adult bird monsters, youth bird monsters, and baby bird monsters. Each have to be sunk once to be killed.

When a bird monster is sunk once, it will produce another bird monster, lower down in its line than it. The exception for this rule is baby bird monster, which does not produce anything when sunk. Once a youth/adult bird monster is sunk, two bird monsters farther down its line will leap out of the water.

Bird monsters do not need to have a loop made around them when moving for them to be sunk, they will be sunk even when moving into a pool of water. Bird monsters are first encountered on level seventeen, where many of them in one of the three different variations are encountered.

Adult bird monsters

Adult bird monster are the highest up in the line, and move fast. When killed, it produces two youth bird monsters. Usually four adult bird monsters are present at the start of a level.

Youth bird monsters

Youth bird monsters are in the middle of their line, being slower than the adult bird monster, and being easier to trap due to this weakness. A sunk youth bird monster will produce two other bird monsters, this one being the baby bird monsters.

Baby bird monsters

Baby bird monsters are the lowest in its line, being the smallest of all the bird monsters and the weakest. They move a bit faster than youth bird monsters, likely due to weighting less. Baby bird monsters do not produce anything once killed.
