Ice Mountain Zone
From Sonic Retro
Ice Mountain Zone is the fourth zone in Sonic Advance. This zone is basically a replica of Sonic 3's Icecap Zone, complete with that zone's snowing effect, albeit with different graphics. It does, however, have a much larger underwater area. It should be noted that, unlike the Sega Mega Drive/Genesis Sonic games, air underwater only lasts for 18 seconds, and there are no chimes to indicate time spent underwater—only a counter for the last five seconds of air.
