Turtle

I want to bring a turtle to my visit with my son.

I looked at some turtles online and a couple were free so I thought they were cheap. I went to the pet store and they're $100+ but $21 for a water turtle but it needs a big tank.

I might get one that's more expensive bc I could do it by tomorrow morning when they open early, however I'm going to see if I can still find one that's free first.
