Super Mario Bros – World 2-4

  • Level type: Castle
  • Time limit: 300

The second castle adds lava to the picture. Podoboos, the fireballs that jump straight up out of the lava, appear over the pits at fixed intervals. Stand at the edge, wait for one to fall back, then cross.

Firebars are back too, and one of them is placed over a pit, so you have to time the jump and the bar together. It sounds harder than it is: the bar rotates slowly, and the safe moment comes around every few seconds.

The fake Bowser here is a Koopa Troopa in disguise, and the same rule as always applies. Jump over him when he is in the air, or run under him, and grab the axe. Fire Mario can end the fight with five fireballs and pick up a big point bonus for doing so.
