Hot Crater is the second zone of Sonic Advance 2. It's a volcanic construction site flowing downhill with cranes and handrails, comparable to Red Mountain from Sonic Adventure. It's a bit trickier than the previous level when it comes to obstacles due to the abundance of gimmicks and bottomless pits.
- Gola - A thing with flames around hit; hit the thing to destroy it.
- Koura - Turtles, akin to the Bane Motora of Sonic Chaos's Turquoise Hill Zone.
- Kubinaga - Long-necked serpentine bots that poke in and out of the ground or wall, spouting tiny fireballs with each thrust.
- Kura-kura - A jellyfish with a tiny flame chain-ball. Just hit the jellyfish.
