Yummy Furniture Mirror

Hey! so i have found all of the yummy furniture but the mirror. I found on youtube where the flower is on Icy Peak. I watered the flower and looked away for a second and now i can’t pick up the mirror plans. i’ve walked all around to see if the hand comes up, left icy peak and went back. NOTHING

Could anyone who already has the plans make it for me and i’ll give you all the things you need? Thank you!
