Seriously! Fire, Bro!
From the Super Mario Wiki, the Mario encyclopedia
The challenge takes place in a castle, presumably Larry's Torpedo Castle because of the background, but once again with the Enemy Course music playing. Like Fire, Bro!, the objective is to dodge the Fire Bros for up to fifty seconds. This time, though, players must avoid the fireballs from both sides, as a pair of Fire Bros are now from both sides, making four Fire Bros in total. If the player is hit by a fireball or touches the spikes and does not have 15 seconds or longer, they automatically fail the challenge.
