These grew very well. I don't mean they filled a bathtub or anything, but the tripled in size or more. Other brands I've seen have bad review for not growing enough, but these worked very well and med our expectations. The kids love them, and they are reusable so they can be grown, taken out of the water and allowed to shrink, and regrown time and again.

Our 3 year old absolutely loves these. So far we've done the alligator and starfish, both were huge within two days. We are doing the sea turtle next. My daughter picks one every two days. Even for an adult, it's fun to watch them grow in water. I would purchase these again!

Cute a little over priced.

Use w cold water only and it takes bout 3 days. But my baby loves watching the growing process!

Items were as described, My 8 and 9 year old boys love watching them grow each day.

My 6 year old grandson put these in a large plastic tub and covered them with water. In 3 days, they were so much bigger, after 5 days, the sting ray was as big as his head! He loves them. So much fun

I assumed like all fairly cheap toys, it would grow a little bit. This this is huge. Through no fault of the toy, we had an incident with the four year old and the tail. This has been mostly in the water for probably 3 weeks now. The huge growth has mostly stopped, but it seems to keep getting bigger. For the price, do it! My husband and I have enjoyed it a lot too!

I was so happy they arrived quickly & were just as promised.
