You bought these two mini nagas. They are clearly struggling a lot in the box at the moment and are trying their best to get out, they were violent in nature. And they were originally set up to be killed and sold as meat, but you bought them just in time before then. You felt sorry for them... The two of them hissed, growled, and made a lot of animal sounds as they scratched and flailed around trying to get out of the box they were in.
