Super NES Classic Edition: Touch Fuzzy, Get Dizzy

How does the wackiest level in Yoshi's Island play on the Super NES Classic Edition? The psychedelic background effect didn't work correctly on Game Boy Advance… Recorded in 4:3/CRT (scanline) mode. (The scanlines don't render well with YouTube compression, I've noticed — what you see here isn't 100% indicative of how the game looks on the actual system.)
