Many Mario playsets note “adult assembly required” (often with labels like “No Tools Needed”). Reviews show a range: some builds are simple snap‑together assemblies, while others have fiddly or complex steps that typically require adult assistance.
Power requirements differ by set. Some require batteries (examples include 2 AAA, 3 AAA, or 4 C), while others list “No Battery Used” or note batteries as optional or included. Check the product details for the exact battery type and whether batteries are included.
