Birthday gift ideas for 3 yr old boy

I am looking for suggestions for an inexpensive gift to bring to my neighbor boy’s 3 year birthday party. His mom said he is working on fine motor skills these days. I don’t have a 3 year old yet so I’m not sure what they would like. TIA!

How about play dough or lego.

Im not to sure about the lego at what age you can play with it I think but dont quote me on it that 3 is okay. You can also get him toy cars.
