Add the exciting Guarded Fortress adventure to your LEGO® Super Mario™ Starter Course! Go across the grass and hop on the catapult to defeat the Koopa Troopa, then jump on the platform to raise the flag. Or leap over lava and beat the Bob-omb. Take the water route to face-off against the Piranha Plant. All 3 roads lead to the POW Block, which opens the fortress gate so you can claim a coin reward!
