The maze is inhabited by deadly "snow bees". They move in a semi-random way: a bee may sometimes choose to get away from "Pengi" instead of chasing him (especially on early levels). The bees can be killed by crushing them with a moving ice block (bees do not stop the blocks so more than one bee can be killed with one kick) or by kicking the fence while they are touching it. This momentarily stuns them and they can be crushed by simply walking over them. Only a set number of bees are on the screen at once (e.g. 3 on level 1) but there are more (a total of 6 on level 1) which emerge from the diamond blocks as others are killed. A level is completed either by killing all of the bees or by lining up the special diamond blocks. This is the preferred way of completing the level because a huge points bonus is awarded (5,000 if they are touching the fence, 10,000 if they are not).
