Goko-Kahu

Goko-Kahu were kind of vulture-like Rahi which lived in Le-Koro. They were a cousin of the Kahu, who, like the Goko-Kahu, were utilized by the Gukko Force. Goko-Kahu were prized by Le-Matoran, who could summon them by flute and, despite their small size, could easily transport a Matoran from one Koro to another.

MNOG
In the MNOG, after Takua had rescued Le-Koro and spoken with Matau, Takua received a flutesong. Takua could use the flutesong to summon a Goko-Kahu to his location. Takua then would be able to move to the Koro of his choice by riding the bird. If after Takua attained the flutesong, and Ko-Koro was chosen as a destination before Takua had ever journeyed there, the Goko-Kahu would be struck by lightning in route, making it necessary for Takua to select different destination.

Set information
The Goko-Kahu model could be constructed from pieces included in the 10023 Masterbuilder set.
