It is very easy in challenge mode however, provided you use the Mootator right away. This skill point is impossible to get on a first playthrough, as you only acquire the Mootator much later, and on a return visit will not be able to find enough crabs to morph. "Do Cows Get Crabby?" is acquired by turning 26 of the scuttle crabs into cows using the Mootator or Armoogeddon. The skill point is awarded upon reaching the largest pier platform where the second boat stops. The crabs also count as part of the skill point, and must thus be avoided or slain. There are in total five guard torsos, one dropped off by the technomite dropship, and two on each of the islands after the one with the scuttle crabs. The Static Barrier is a near-guaranteed success if it is used as you are not allowed to take damage, but being hit is fine. This is easier to do after going back to the planet, due to the reduced amount of enemies, and especially with improved equipment. "Don't Rock the Boat" is acquired by completing the entire boat portion at the end of the " Rescue the girl!" mission without taking damage. Alternatively you can return later, with stronger equipment, and outright ignore the enemies to rush through the entire path.
This does not have to occur during the mission, and can be done straight after when all enemies have already been removed. "Train Faster" is acquired by beating the training portion of Jowai Resort, effectively the " Fight some robots" mission, within 92 seconds.
