It means Before you open the bunker, do not go LRRR in the forest, go into the Ice cream lab, and teleport via TP3000
ok
more like, can i go get infinite money from the ice cream lab at the start of the game or i can't in no time? and if i can't go either at the beginning or at the end, how can i get over 500 rubies without that?
You can go there after you open the bunker and still obtain the Bunker ending, plus it's required for the Secret ending
