Good buy
These are very surprising. We doubted that they would actually grow 600%, but lo and behold, just after 2.5 they grew so big, it was such a wonderful surprise. My 5 year old grandson and his 3 year old sister were in awe and giggled with joy. I highly recommend these toys. I will be purchasing more for my local elementary school Good News Club "store" as prizes for learning Bible verses.

Great for growing, but won’t stay that way…
We have only soaked the crocodile so far. It took a week for it to grow to its full size, but the croc is now leaking water and has lost about 1/4 of its size. These are great for growing, by far the best we have tried and truly grow big, but these aren’t something you will want to keep around. I’ll update if anything changes with the other animals.

As expected
As expected. My grandkids had a blast “growing” these!

My kid wakes up every day and wants to see “did the starfish grow?!”
Took ~4 days for the starfish to grow fully. Toothpick for scale. I put it next to an ingrown crab so you can see how much it grew. It became a daily event for us to check it each morning to see how much it grew. It gets a little slimy but if you aren’t handling it and just letting it sit in a bowl it won’t matter. I put the crab in a bowl after the starfish was done and the crab grew MUCH faster. Doubled in size in 10 hours.

HUGE but does not lasts.
These creatures get HUGE. I would rate it with 5 stars for that; however, the bigger they get, the more easily they break apart. And that part upsets the kid. Grows big just to fall apart. It's pretty cool, just REALLY keep in mind the end game to it.
