The egg format is what sold me — my nephew tore through all 20 in one afternoon and every single one had actual buildable parts inside, not junk. The mutant vehicles ended up looking weird in the best way, and he's already asked for more.

The build-a-vehicle twist kept my son busy for a solid hour, and he was genuinely excited each time he cracked open another egg. Twenty capsules means the fun stretches out over several days instead of being over in one sitting.

Bought the 20-egg box for my nephew's birthday and it kept four kids busy for a solid hour. Each egg has the parts to snap together a little mutant car, so the building is half the fun. Only gripe is that a couple of the pieces fit pretty tight for small hands.
