Bullfrog help

Hello, maybe not the wisest decision to take a live frog home from the Asian grocery store but my kids begged and I'm up for the project I think. If anything, it's better than him being killed and eaten i hope lol. We set up this large outdoor enclosure for him from a big gardening bed I already had. We put a fine mesh over the top that is removable to keep him in. Any advice on the setup? It's just what we had at the moment. We are planning on bringing him inside at night if it gets too cold. We've got an extra large Rubbermaid container. Please don't be rude, it was in a tank with a hundred other frogs about to be killed. Yes I understand me buying one is supporting the process and not really helping the cause. It's been a fun learning project for the kids and he's here now, so 🤷‍♀️ thanks in advance!! (And yes planning to do a water change every day)
