Too difficult to okay with. The "shell" was too hard for a kid to carve

This is a gift for Christmas, will follow up with a review later.

It's a bit messy but it warns you on the packaging. It's a lot of fun & their are informative cards about each animal. My 7 year old son Absolutely loved this product! Strongly recommend it to the little animal or science lover in your family!

My 6 year old grandson went through all the eggs without stopping for a minute. The directions say soak first which makes sloppy mud. We skipped the soaking and and the excavation went just fine with less mess.
