Click the see inside button and go in costumes. Then spam the convert to vector and convert to bitmap buttons until it turns into a pink box. Make a remix to show me the pink box. There is also another glitch where if you keep spamming convert to bitmap and convert to vector the scratch cat goes off the screen. Both glitches work with most costumes.
UPDATE: This is me from May 10, 2021, not sure if this works anymore because of Scratch 3.0
