Strich

Strich, along with Cawlin, is a student at the Knight Academy and a friend and henchman to Link's personal rival, Groose.

Biography
He, Groose and Cawlin have a reputation for being bullies. During the Wing Ceremony race, he will throw eggs at Link to help Groose win.

Strich can be found in the Lumpy Pumpkin during the day, and in his and Cawlin's room at the Knight Academy at night. He has an affinity for bugs and is willing to buy them from Link. However, he will only buy three varieties of bugs on any given night, according to his mood. Near the end of the game, once Levias has been released from the control of Bilocyte, Strich can be found on Bug Rock in the thunderhead, where he runs a bug-catching mini-game known as Bug Heaven.

When Beedle's precious Horned Colossus Beetle goes missing, Strich is revealed to have found it. He refuses to return the bug unless Link collects ten specific insects under three minutes.

The prices he gives for certain bugs are as follows:

Etymology
Strich's name most likely comes from the word Ostrich, as most Skyloftians are based and named after birds.
