Thanks for the help. I was able to find the missing pistons and get through that door. I've now gotten through a few things I was struggling with. I'm still missing several souvenirs, an H-Scene, and 3 monsters. Getting much closer to 100%.
Souvenir #7 I can't recall for certain but I think that was found in the mountains. It's the hermit fruit. The cave/shelter where Hannon and Eliza have an H scene.
Souvenir #17 is the exploration crab but I can't remember where it's obtained.
Souvenir #33 is one I'm lacking myself.
Souvenir #46 you have to take Zashiki (No. 26) to the puppet maker found in the adventurer's town. The hut that has the blacksmith and the bartender that need a monster or ticket.
I'm currently missing Souvenirs #13, #19, #25, #26, #29, #30, #32, #33, #38, #43, #47
I'm missing Monsters #79, #80, #87
I'm missing trap #20
Also I can't seem to find the skull jar which is the last item I need to finish with the requesting fairies.
I found all but #7 its not the one in the cave i already had that. It has to be somwhere around the 2nd town i guess ill try looking for a fruit.
Do you know where the Monster #150 is? Its Probably some kind of Boss. I have a suspicion that its in that hole between the Spaceship and the Last Dungen of the Main game but i dont know how to get there.
Monster #79 and #80 should both be on the Spaceship normal encounters
#87 should be in the last dungeon of the main game as a normal encounter
as for the souvenirs the #33 is kinda embarrassing to miss i have to admit myself its in the bottom left building of the futanari fairy city in a fucking box ^^
#32 is also in the fairy city though i dont exactly recall where
#13 is called Sulfur Stone but i cant recall where it was
#19 is golde Toori gate. I dont remember exactly but it should be somwhere in the teleportermace in the way to the Spiritgirl. Either in the Dungen or outside of it. Its somwehre in that area for sure.
#25 and #26 should both be somewhere in the knights city where you have to dress as a knight
#29 Larg Charcoal if i remember correctly its in the firedungeon and you need the Monster Cokeball to get it.
#30 Is called Slimy Octopus its either in the firedungeon as well or on the way through the canyon.
#38 Gritty Paper i think its in the Knights Headquater in the last checkpoint before the fight with Pufiru where you can change the fur and hair for items.
#43 You need to go back to where you beat Pufiru and get the item lying on the ground. After that go back to the checkpoint a mentioned before and trade one of the girls for it.
#47 is where you safed Leroux and the shrine maiden. Just go back there and go all the way south. If its not there it could be at the spot wehre the final boss of the aftergame story was but i am pretty sure its there.
Trap #20 should be somewhere in the aftergame dungeon its probably those magic circles on the ground. if you teleport with the crystal and then go all the way back until you cant go south anymore ther should be a long corridor. Thats where they are.
