Intaking a substance like this will cause direwolves to become excited and playful, and sometimes, aroused. However, these effects will wear off in at least two hours. Fermented Liquor Chocolate is packaged in golden strips with a red-wine color label. All Direwolves can also eat chocolate of any kind, not just Fermented ones (and dogs in general).
