I'm trying to get good at the Squid Scooter shortcut. With Strange Drink. Fish and Ammo Crate, but I always get stuck at the entry point of the plane(the hole just beside the plane touching the left wing) before losing vision and drowning. I've watched speedrunning attempts to grasp how they do it so seamlessly, but I still struggle. Is there any tips and tricks I haven't been using that would help with this shortcut? Thanks!
