So my fiancee gifted me a bumblebee ball python.

He will be coming in on Tuesday, and I will be preparing for his arrival over the weekend. But I do need help- you see, I got my female when she was an adult; I've never had to care for a baby snake. I believe he will be in the 140g range. What, in your opinion, will he be needing? Fuzzies? Hoppers?
He will be staying in a very nice wooden snake box; a barista at my local coffee shop gave me it for free

The measurements are 32 x 15 x 15 on it; it has some sort of hard white plastic looking board on the bottom (pressure board?). Is that okay to put a heat pad on? There's a hole on the top of the wood for a heat lamp too
