since people cant be clear enough on this get a cup of water from the watercooler in the room with muffets fight then go to the room with the door puzzle i think its the one on the left in the room with the flower right after you leave the bedroom with chara keep following th sound with water in your inventory and youll find a shy shadow girl after a quick and easy fight with her use it on her plant and get the carrot i recommend saving before muffet incase you use the carrot incorrectly survive one turn against the bunny shadow in muffets fight and you can use the carrot to end her part of the battle just keep going for it in that puzzle room i swear i was starting to believe the carrot was a psyop since this community is a whole vaguepost kingdom
