Jetboard Jetty

Jetboard Jetty is the third and final story level of Salty Wharf and the ninth main level of Crash Bandicoot 4: It's About Time. The end of the level includes a surprise boss fight against a tentacle monster named Louise. To defeat her, the player must lure the swordsman rats towards her tentacles. The second quantum mask Akano is found after completing this level.

Overview
After meeting up with an alternate version of Tawna, Crash/Coco enter a pirate grotto filled with treasure chests and loot. They use the jetboard to traverse through the ocean floor, while encountering a sea monster named Louise near the end. After they successfully defeat her, Crash and Coco make it to the sleeping Akano.

Crash picks up Akano while ignoring Lani-Loli's warnings about Akano being extremely heavy; causing him to slam onto Crash's foot while crying out in agony. Eventually, Akano awakes to find Crash and Coco and starts intimidating them. Fortunately, Lani-Loli tells his brother that the bandicoots are here to help save the multiverse. Akano starts warming up to the bandicoot duo and instructs them to follow him. Lani-Loli shows great enthusiasm for Akano as they enter the quantum rift to the next world.

Trivia
