Try piloting the prawn suit all the way from spawn to the bk trench, down into the lost river, to the tree cove, to the ILZ, and finally to the lava lakes and to the bottom of the Emperor's tank and then ALL THE WAY BACK. Bonus points of you do it from experience without watching a tutorial/having beacons.

(I've done it before so its very possible just a bit time-consuming)

Ofc you have the grappling arm, storage, jetpack and engine efficiency upgrades
