Add a new challenge to your LEGO Super Mario Starter Course with Whomp's Lava Trouble Expansion Set! Avoid falling off the sliding platform into the hot lava. Knock over the Whomp guarding the P Switch and then you can win a shower of coins for running, jumping and doing stunts with LEGO Mario (figure not included). Just beware of the Lava Bubble - you'll need the Green Shell to knock it over!
