Step 1: Begin your run like normal, start with forest and do the run as usual.

Step 2: When you return to the chef tent for the memory, grab the "I Cant Believe Its Not Tuna!" Can.

Step 3: Finish the forest run.

Step 4: Its gambling time! During the geyser cutscene, Open and close the container until you get a jar of coolant. If you don't get it then, try doing it during the cutscene when you first enter the beach.

Step 5: Go to the beach and use the coolant how you would in the run normally!

Step 6: Finish your run!

This skip that i think i discovered saves the time of getting the coolant from the vending machine and is very useful (at least for me!) Thanks for reading!
