Hot Mobile

From Sonic Retro

Hot Mobile is the Lava Reef Zone boss for Sonic and Tails (Knuckles skips this boss and moves straight on to Hidden Palace Zone). When reaching the end of the Zone, Knuckles will knock a bolder at our heroes, sending them down to a lava crater and knocking them out of their Super or Hyper States. Dr Eggman will fire four sets of paired rockets while the screen auto scrolls to the left. It's advised if you can use your Super or Hyper transformation, that you don't do it now because you will need delicate movements to transverse your way through the autoscrolling madness of a set of regular platforms targeted by the missiles and a set of collapsing platforms thereafter. Eventually you will reach a checkpoint followed by a lavafall. Four descending platforms await your (forced by the autoscroll) leaps across. On the fourth platform the autoscroll stops, allowing you to jump down to get a Lightning Shield. Use it to jump left to find a Fire Shield. Ride another one of the small platforms down to the boss.

Dr. Eggman will emerge from the lava and cause it to tilt, making the platforms you're standing on ride into his mobile shattering them. He will fire mines in the lava in the gaps between the platforms, three times a round and then change side after they have depleted. Your job is to jump from platform to platform while avoiding the mines while they hit Eggman instead. This boss battle is made easier if you can walk on the Lava with your Super State or Fire Shield. After 14 hits, Eggman is defeated.
