3rd pic = Ice boots for platform, switch to pig form & buttstomp them to form the pattern from the mural. Solution is:
Start at the left geyser and pound it down twice, then the second from the left needs dropped one. The third geyser can be left alone and the one on the right needs pounded down three times. If quick enough, the door to the left will open
