The Cave of Snarls is the nineteenth level in Challenge Mode in Pikmin 2. Since the Male Sheargrubs are the only harmful enemies, a pink flower is almost certain. This level features both airborne Blowhogs.
The Withering Blowhog has The Key again. There are some mechanic parts sitting around, such as the Network Mainbrain. The Key can either be taken directly at a risk or after defeating the Blowhogs. They should spawn close together, so bitter sprays should be quite effective.
