Odoru Ponpokorin (おどるポンポコリン) (9*; 504 notes)
Fresh from the latest song pack, this new Oni mode for the Chibi Maruko-chan opening theme scores a 9-star extra Oni challenge with a barrage of old-school 1/16 clusters with no modern gimmicks spliced in, for a brief yet intense stamina challenge not very much dissimilar to No Way Back's regular Oni.
