Make a hole in the middle of a Nabicon and Blue Pupa won't be able to come out of it.
Some Nabicon can be destroyed when Motos is outfitted with at least five Power parts. You can tell this when the Nabicon shakes as Motos bumps it. Bump a Nabicon more than ten times and it is destroyed, scoring you an enormous number of points (see Scoring above).
