Mecha-Zinger, as seen in Donkey Kong 64
Mecha-Zingers were introduced as a variation to the generic Zingers. They are purple and yellow robot Zingers that can only be encountered in Donkey Kong 64. They are only found in the Frantic Factory area of the games and they will show up in a mini-game in Hideout Helm. They will try and attack the Kongs by dropping unripened green Orange Grenades. They are also a bit tougher to defeat from normal Zingers. They will not try to dive-bomb the Kongs. They will need to be hit twice before being defeated. When they are hit once, they will start to fly erratically and smoke. Instead of wings, Mecha-Zingers have propellers.
