Hey, i just got Jenka's fourth dog outside that place with the locked door (And the hidden Save and Restoration above the doggy), i hopped off of where i got the dog, i was messing with the Machine Gun, firing it randomly, and in mid-air, firing it downward, it propelled me upward, this can only be done by the level 3 Machine Gun due to it's blasts being powerful :D
Even if most of y'all already knew this, i just found it out and just thought i'd mention it, along with some minor progress
