Glugging all from the deep collection
Gluing from the Deep consists of nine collectibles, including newspapers, baseball cards, plans, and figurines. The list below shows a complete breakdown.
- Newspapers: 1
- Baseball Cards: 2
- Planning: 5
- Statue: 1
- Total Collection: 9
Go to the docks and enter the harbor area
Planned
At the very beginning of the level, go forward and to the left on the crates. Then jump towards the Warp-Pipe and use it to fall over the pipe attached to the wall. Go through the window and look right to find a schematic on the table.
Baseball card
Go back through the window and back to the ground where you started. Go down the stairs, enter the factory room, and defeat all the enemies to make a trampoline appear in the northwest corner. Before hopping on the trampoline, use the vent next to it to reach the baseball card.
Now use the trampoline to reach the scaffolding. Cross the gap, go through the hallway with the typewriter, and proceed to the exit. Go through the corridor to reach a small flight of stairs leading to the docks.
Find a way to dive underwater in Firth Harbour
You must collect the Heavy Steel Boots, Rubber Suit, and Eddy's Diving Helmet before you can go underwater.
A can of sea slugs
At the bottom of the stairs, go forward and to the left to find a Can of Sea Slugs in a shipping container. Check out our slugs in shell walkthrough to learn more about this item.
Newspaper
Look at the small boat on the water. There are cracks in the boat wall, and you can use D-Namite to destroy it. Go through the warp-pipe that reveals to find a newspaper on a crate.
Planned
Use the warp-pipe to return to the docks and climb the stairs to the south to reach the switch. Flip it, turn around, and jump to the top of the rail on your left. Jump to the next platform and flip the switch to move the crane.
Use the grapple tail to swing from the crane to the roof. Use the tail-a-chopa to get around the large tank and onto the chain link platform. Walk up the sloping roof to your left, jump through the vent in the wall, and follow it to find the schematic room.
statue
Backtrack through the vent, drop to the floor, and climb up the ladder you used to reach the first switch. Jump over the railing to reach the roof and walk all the way to the end, jumping over the partial fence that stops you. Finally, drop down to the wooden slats to find a secret room. A statue will appear here after Veloper stops talking.
Use the warp-pipe in the figurine room to return to the docks. Go through the large opening next to the ladder and follow the train tracks to the hungry pelican. Go in and talk to Tammy.
How to get heavy steel shoes
Planned
Flip the switch next to the typewriter on the Hungry Pelican and interact with the Warp-Pipe that opens to return to the docks. Go to the train car to your right and talk to Eddie to get the Heavy Spiked Boots. There is a schematic on top of a crate in a train car.
How to get a rubber suit
Go to the Hungry Pelican once again, but don't enter. Instead, go forward and to the left to reach a small staircase. Cross the gap below and enter the door on your right. Climb through the industrial area and look to the right as you enter the last room to find a rubber suit against the wall.
Get Eddie's diving helmet
Baseball card
After defeating the enemies that appear, go through the opening in the northeast corner of the room and head left. Go to the empty space and look in the shipping container to find a baseball card.
Cross back over the gap and go down the stairs to your left. Follow the main path back to the docks and reach the bottom of the stairs you used to enter the area earlier. Here you'll find a warp-pipe, and the diving helmet is in the room you get past it.
Return to Tammy & Dive Underwater
Use the warp-pipe to return to the docks and get to the Hungry Pelican one last time. Talk to Tammy and go to the cage to drown.
Search Ze Submarine
Planned
Now that you are underwater, follow the main path through the angler fish area until you have to go through the shipping container. When you come out, look right and climb the stairs ahead. Follow the alternate route to the top to get to the planned safe.
Poke around the basin
Continue forward along the alternate path to reach an alcove with Sleeps with the Fishes. Talk to him. See our friends on Deep Spaces to learn more about this interaction.
Return to the main path and approach the submarine. Use the warp-pipe to enter it and face the Ze Professor.
How to beat Ze Professor
Follow these steps to beat Ze Professor:
-
Shoot the orb turrets on the wall until they blow up. This will spread force fields around the pipe in the room.
-
Destroy all the pipes in the room.
-
Repeat this process in subsequent rooms.
-
When Ze Professor appears, shoot him until his health drops to zero.
Take the Ze professor's note and escape from the Ze submarine
Planned
Take the cue left by Ze Professor, flip the switch in the control room, and enter the diving suit to release the sub. Before interacting with Jack's car, look on the ground with an angler fish to find a blueprint.
Drive back to the office, wrap up the case with Wanda and Curry, and pin down the rest of your missing wizard clues.
Back in the PI office, talk to Wanda and Stilton in Little and Big. Also, talk to Cameron and John to complete Friends in the Deep Spaces and Slugs in the Shell Side Tasks. Then head to Jack's office and pin your clue on the crime wall to complete the gluing from deep.
