Zingers

Zingers are a reoccurring enemy in Super Luigi Country. They are the main enemy of the game and show up in some levels. The levels they appear are levels 1, 7, and the boss fight with Captain Olimar. They are reoccurring enemies in the Donkey Kong Country series by Nintendo.

Level 1
There is a Zinger placed in front of the first two blocks below the platform, he is very easy to avoid.

Level 7
There is a row of 4 Zingers heading towards you which you have to get to the balloon to avoid.

Captain Olimar Boss Fight
The Zingers in the Olimar fight try to prevent you from reaching the Super Mushroom on top of Olimar.

These Zingers were probably shrunken by Kamek with Luigi.
