An orangutan named Malu escaped from his cage on Monday thanks to an impressive use of tools.
Malu, who lives at the Melbourne Zoo, used a blanket to break through the roof of his enclosure. According to Australia's 9News, Malu wrapped the blanket around the top bars of his cage and used his weight to break them open.
Once his cage was broken, Malu was spotted strolling across the roof of his outdoor enclosure and onto the roof of a neighboring building. When park staff were notified, 9News reports, they ushered zoo visitors into a cafe and put the park on lockdown.
Zoo staff then tranquilized Malu and returned him to his cage. "He'll wake up tomorrow morning not knowing exactly what happened, but thought he had a good time," zoo director Kevin Tanner told 9News.
