frog identification

[riddlebox]

Hello everyone
I am new here and im not sure if i am posting this in the right place so sorry if im not. I found a frog at the greenhouse i work in and im not sure what kind of frog he is. We are going to be turning part of the greenhouse into a fridge for our festive greens and a lot of our tropicals are getting moved out to make room. I am concerned the little fella will freeze here because he came in a tropical shipment of plants so i was thinking perhaps i could build a home for him but i want to make sure i do it right so hes happy. If anyone could help me identify this guy and give me some advice on his care he and i would greatly appreciate it. thanks !!
