Items

Power-ups are introduced in Gravity Falls: Undersea Expedition, along with collectibles returning from the first one. 

Collectibles

Image Name Description Usage
Stan Bucks Stan Bucks are like the coins of this game. They are found in every area's levels, minus some of the challenge levels. When 100 are collected, you get an extra health bar. They can also be used at McGucket's Weapons and Wares as currency.
Plastic Skulls These cheap plastic skulls are actually the best collectible to find. They are found in every stage, but are incredibly rare. Plastic Skulls unlock challenge levels and can be converted into 1,000 Stan Bucks at McGucket's Weapons and Wares.
Journal Pages Some journal pages from books 1, 2, and 3 have fallen out. These are found in some levels, but not all of them. Journal Pages can be used to add on to your bestiary and biography section of the journal. Once you collect all of the ones from Books 1 and 2, the Mysterious Bunker area opens. The Book 3 pages open the Retro Dimension area.

Power-Ups

Image Name Description Effect
Crystal Crystals are similar to Mushrooms from the Super Mario series. They can be found in chests all over the level.  Adds an extra heart to the life meter. 
Super Seaweed Super Seaweed is similar to the Frog Suit power-up, but not as cool. It turns the character that gets it into a water creature (a human in Mermando's case). Turns the character into a mer-person; mostly found in underwater levels. 
Smile Dip Packet Smile Dip Packets are some of the rarest powerups to get your hands on. They can only be found in 10 levels, including the first level of Smile Dip Trip. Causes the background to go crazy because of the Smile Dip and grants the player invincibility from about everything.
Clone Chocolate Mmmm...chocolate. This chocolate, however, adds a clone of you into the game. Imagine one million Mabels! Creates a clone of the playable character you chose.
Ninja Suit Ninja Suits are an original power-up that boost stats in every way possible. They are most useful for Soos. Allows the player to throw shruikens and boosts all of their stats to the max.
