1. Dark Blue Moon does not control water, it is an aquatic stand with webbed hands, fins and a few features/abilities to take advantage of underwater combat environments, instead of actually controlling/manipulating water in any supernatural fashion. Hopefully that is making sense, it's like the relationship between wings and wind.

2. Horus is a bound stand attached to Pet Shop's body, being what we call the "ability stand", as they give the user special abilities instead of being a wraith doing things for the user upon being commanded.

As such to answer your question I would say that, it can be both. It can be either that Pet Shop is able to produce ice on its own or that it has to rely on existing moisture in the air. this is completely depended on what Araki's definition of "Cryokinesis" (ice control) is.

However considering its fight with Iggy got way hella mroe intense than before after they got into the sewer system I would probably bet that at least to some degree, Pet Shop still relies on the moisture in the immediate surrounding to produce ice.

As mentioned before, DBM doesn't control water. Considering N'Doul got burnt after Geb had a portion of it evaporated by Magician's Red, I would imagine if Pet Shop were to freeze over Geb, N'Doul would most likely be damaged too, either being frozen and unable to move or receiving frostbites.
