Just like in Faster Fort Fire Bros., when the characters begins the level, they only have 30 seconds to get through it while picking up + Clocks and dodging Spiny Skipsqueaks, which replace regular Skipsqueaks, and Spinies from Really Rolling Hills, which are randomly scattered throughout the level.
