ye that might be a glitch,tho no worries,you can still get through the area ,by activating no dripping :P Basically pressesc and go to the cheats,then active no plant dripping.Tho if you want to get through the plant minigame without cheats,try pressing new game,or just redonwlad the entire game.
(also for some reason i cant post pictures of that process ,so you will have to go by the text).
