Use the slow global crab and Skulteras to get up. The last part, just below the item is the hardest. Wait for the global crab to be on vertical portion the ledge jutting out on the right or left - any other locations and it will fall on a platform and get stuck. Shoot a super and freeze it mid air. Using the frozen crab on the platform, the mid air crab, and the fish, jump up to the solid ground. Freeze the Skultera at the left, near its minimum and jump to it, then the solid ground. Note that the fish will be pushed down slightly over time because of the sloped tiles, but it will be at its minimum by the time the global crab has arrived.

After the global crab passes and starts climbing up, use a super and freeze it mid air to get to the left platform. Jump and a quick crab will start moving down the right wall. Quickly shoot it and freeze it to get over to the right. Wait a long while for the global crab to return. Let it pass, then use a super to freeze it mid air and get to the next platform. Follow the global crab the rest of the way up to the door while using it and the fish as platforms on the way. For a faster but tighter strat, knock off the first downward moving crab with a super and follow it up while freezing it and performing precise platforming.
