Serpent bubble guardian

snake bubble guardian (all credit to

The snake bubble guardians are caterpillar-like serpents from Serpent Shrine. They have 3 unprotected creature brains, spikes on their heads and tails and always have some prize bubble underneath them. They also carry their own prize bubble.

When a Sackboy or Sackgirl encounters one, he (or she) must jump atop it's back and jump on each of it's three creature brains, it will then fall apart and disintegrate and the Sackperson can grab the prize bubble that the serpent was guarding.
