Hi love the game! But I do have a question and maybe a bug report? For context I am more of a butt person so I wanted to collect all the bottom cave food but I ran into a snag getting the food from the other two biomes. So how do you get to the bottom cave food that's on topping mountain? I found where they were I just couldn't see a possible way to get to them w/o a jump boost. As for my bug report (though not sure if it is a bug) the beanstalk in the jungle won't grow even if I visit the area and leave, it always says it'll be grown tomorrow. So currently there isn't a way to only get butt gains. I hope this helps!
Hmm. The jungle's stalk grows just fine for me in testing. Both it and the cave progression blocker require you to pick up at least one ingredient before leaving, but given your situation I would imagine you may not be doing that, hence running into issues? o: Do make sure you're on v1.7.0.1 please! (I should probably add a version number on the startup screen-- in order to do this you either have to hover over the executable and check its "file version," or if you're using the Itch client just click the settings gear next to "Launch" and then the "Manage" button on snack-wanderer-windows.zip!)
For what it's worth, each part can only be fattened so many times, and the butt ingredients from either the Jungle or Mountain alone are enough to max out the butt after Bottom Cave becomes unavailable. So I guess just pick a secondary part to fatten and grab some of those. You could also intentionally only pick up one boob/belly ingredient & then leave if you'd rather not see another part grow c:
