2 player combat or platforming toy boxes for young kids

I recently got Disney Infinity 3.0 for my kids (3.5 and 7 years old) and they find that they enjoy the toyboxes with very straight forward combat or platforming the most. They tend to get stuck whenever there are any weird puzzle elements. What is the best way to search for the best ones? I've tried downloading a few from the searches but often they don't work well or are only single player and it takes so long to download and start that its really slow going. Are there any articles or documentation listing out some of the very best toy boxes for 2 player cooperative combat or platforming?

Thanks.

What console do you play on?
Also have you looked into marvel battlegrounds? It might be perfect for them as they like combat or the inside out playset is great for co op platforming as well
