Stuck, shaking item

From Glitches

From the game Super Mario World for the Super Nintendo

You can get items like P-switches and springs stuck in solid spaces. You have to be riding Yoshi to do this. Grab the item with Yoshi's tongue to put it in his mouth. Now, walk to the area of solid blocks. Spit out the item and it will sometimes be stuck in the blocks, quivering back and forth.
