What is the primary addition to a Hairy Navel compared to a Fuzzy Navel?

The Hairy Navel is essentially a variation of the Fuzzy Navel, and the primary distinction between the two cocktails lies in the addition of vodka to the Hairy Navel. The Fuzzy Navel is a straightforward mix of peach schnapps and orange juice, providing a sweet and fruity flavor profile. By incorporating vodka into the Hairy Navel, it adds a more potent alcoholic element without significantly altering the overall taste, enhancing the drink's complexity while still retaining the fruity characteristics from the peach schnapps and orange juice. This makes the Hairy Navel a stronger and more layered drink compared to its counterpart, the Fuzzy Navel.
