Alg boated his arms slightly for the pine marten, holding Gloom much like you would a cat. Alg was not good at saying no to things even if in the back of his mind there was a voice screaming not to let supernatural creatures run freely in his shop... but better he lean towards good will, especially when Gloom seemed to be rather sweet.
And Algie was susceptible to cute things.
"Yes, it's alright. Just remember to be nice to the books," Alg remembered the book Gloom had stood on and how upset the creature was at the thought he'd hurt it. "And I have a cat so no trouble- unless you know her, I don't really know." Did magical animals know each other?
"She doesn't get out much."
