Bottomsup Bay is a Dig Site well guarded by schools of ferocious Denture Sharks, this area is said to hide a pirate ship sunken long ago. Only Level 4 Fighters are allowed access. Its Area Guide is Nancy. This site introduces Captain Woolbeard and his Pirate Ship. Obviously, since it is underwater, it mostly has Water-type Vivosaurs.
An asterisk (*) indicates a Vivosaur that is rare.
Bottomsup Bay is where the third Tacky Idol is found. The player must make their way past the Denture Sharks and search each sinkhole until he/she finds a sunken pirate ship. The player has to enter and work his/her way through the wreckage until he/she makes it to Captain Woolbeard's quarters. He asks the player to find his beard ribbon, which the player must ask Mr. Richmond about. Mr. Richmond says that his friend Nick Nack, who lives in the Hotel, has it. Nick Nack says he will give the player the ribbon if he/she acquires three other objects in exchange:
1. The first, a molted bug shell, is in Knotwood Forest. However, before the player can get to the Digadigs, Rex must be fought. The chieftain has the player do the hip-shaker dance to free a bug from its shell, allowing the player to claim it for Nick Nack.
3. The final item is a set of dentures from a Denture Shark. Avoid the sharks, and enter the obvious cave. A shark abandons his teeth, and the player must receive a Smashing Success cleaning in order to clean off the gunk.
After acquiring these three objects, the player must head back to give them to Nick Nack. However, Vivian is blocking the elevator in the Hotel, and must be defeated. Nick Nack rewards you with the beard ribbon, and you head back to Woolbeard's ship. The BBs are already there, giving him a fake ribbon, causing him to become extremely angry. With no way of calming him down, he must be defeated in a Fossil Battle. He rewards the player with the third Tacky Idol, which is what the BBs wanted.
