LEGO picked this idea and took it to a whole new level with their ingeniously crafted building block sets. The Super Mario set remains one of their most popular offerings to date.

There are 133 pieces included in the set that allows you to build obstacle courses for the Super Mario figure to overcome. It is the only Super Mario LEGO set to have a P-switch.

I should mention here that the Super Mario figure isn’t included in this set. It’s only available with the LEGO SET 71360, also known as the starter kit. Whomp’s Lava Trouble Expansion set is basically designed to be an extension of the Starter kit.

If your child is a Super Mario fanatic and already owns multiple Super Mario sets, the Whomp’s Lava Trouble Expansion set will be a perfect addition to his collection.

It’s LEGO, so the quality of the blocks is undeniably top-notch. Another thing I really love about this kit is its affordability. Legos aren’t really cheap compared to other brands but this kit goes pretty easy on the wallet, making it an ideal birthday or Christmas gift for school-age kids.

The foundation of the structures are magnetic bars and balls. The magnets are quite powerful, allowing the blocks to stick together really well. If you are looking for a fun way to introduce your kids to the fascinating world of geometry, this would be a great option to look into.
