Tip: When determining a time limit, remember that players won't be as familiar with the level as you are. If you normally complete the level with the timer around 100, others might run out of time on their first try.

SMW Music - Sonic CD (JP/EU) - Collision Chaos Zone (Present)
The bouncy second level theme from Sonic CD. Or third, considering this is indexed as R3. Regardless, it's supposed to be a casino level, so you know how to apply that to Mario. Uses noise, watch out for those noise SFX. Can also be prone to SFX cutoff in parts.
