Piler

'''"This is why you don't see me at the beach often." - Wambus'''

The Piler is an aggressive Bugsnak resembling a blueberry pie and a rhinoceros beetle. It is found at Simmering Springs.

Strategy
2 Pilers are seen wandering Simmering Springs. Lure them to a hiding bush with chocolate, causing them to run at the bush. This will stun them, and you can scoop them up with the net.

Another method is to coat one of the Pilers in chocolate. Similarly to the Bunger, another Piler will rush over to the Piler to playfully tackle it, and you can scoop it up in your net.
