Grubbs learn Silver Bubble, a Larval-type technique. They can also use any Larval or Insect techniques that their ancestors learned.


A Grubb will evolve from a Terra Egg after one battle, as long as it isn't in storage. It will evolve again at level 5, becoming one of three beasts based on its actions in battle:

  • If it used mostly physical attacks (at least n%), it will become a Gobbldegak.
  • If it used mostly magical attacks (at least n%), it will become a Terrnip.
  • Otherwise, it will become a Chakasi.
