Turns out there's even more LEGO Super Mario content than originally revealed last night. If you are planning to grab a preorder of the LEGO Super Mario Starter Course, then you'll be getting a bonus set along with your purchase.
The Monty Mole and Super Mushroom expansion set can be seen above, which includes interactions with Stone-Eye and Monty Mole. The Super Mario Starter Course is required for this set to work. You can check out more pics of the set here.
