Query: Not a good purchase

After filling this for the first time and setting it up we noticed that all the water in the tank just leaks out the bottom of the unit. That's an entire gallon of liquid on your table in about 2 minutes.I've since checked online and others have had this problem. Looks like some of the units crack inside and the water just flows out of the base.It looks cute but that is even worse if your little one wants to know where his penguin is and why it can't be in his room.Avoid or at least check other reviews.
