Buggie

Buggie was an entomologist who worked at the Ardougne Zoo. According to his diary, he was ambitious to get the zoo to give him a display of insects, who refused and mocked him, preferring big creatures like wolves and cyclopes. Buggie proceeded to search for the Kalphite insects in the desert, hoping to convince the zoo to give him his own exhibit.

He stole kalphite eggs from the Kalphite Lair and prepared a cave with sand to cover the cavern floor. However, as the kalphites grew larger, they grew more aggressive, and one of them bit Buggie. Assuming they aren't poisonous, he ignored it.

Soon enough, he began to experience headaches and hallucinations, and eventually succumbed to the poison, as is evident to his corpse in the Stronghold Slayer Cave.
