Hello,
If you beat Mom Piranha (because Thunderhand is the only item needed to unlock) before beating Chuckolator (which required Beanbean Brooch and the 3 Chuckola Fruit), the cinematic of Peach that land doesn't show (and i suppose that the trigger for beating Mom Piranha) and Mom Piranha is not considered as "Complete" even if i unlock the shop AFTER Chuckolator. Some run i've done was softlock because they need an item from the shop... that doesn't show even if i complete the boss.
