Gypsy

Town Merchants
Gypsys merchants can be found walking around most towns or inside homes. They offer a variety of services and unlike the villagers are usually no-nonsense.

Ferryman
The Ferryman will offer passage down the Dead River to Simon Belmont to the Town of Aldra. If he is presented Dracula's Heart, he will take Simon to Brahm's Mansion.

Oak Stake Merchant
Residing somewhere inside each haunted mansion is a gypsy merchant who offers to sell an Oak Stake for 50 Hearts. This stake is needed to obtain the relic housed in a mansion

Graveyard Gypsies
The graveyard gypsies appear in graveyards in Castlevania II: Simon's Quest. They love garlic and will appear to Simon if he places it in the correct location in a graveyard and give him an item. The one in Camilla's Cemetary is summoned at the western most point of the cemetery and gives a Silver Knife as a reward. The one in the Storigoi Graveyard can be summoned at the dead-end of the westernmost point of that cemetary. It will give give a Silk Bag as a reward, which will increase the capacity for Simon to hold Laurel.

Altruistic Gypsies
There are some Gypsies that can be found outside of towns that give Simon something for nothing in order to help him defeat Dracula. There is one that gives him a supply of Laurels, one that gives him a Diamond, and one that powers up his Morning Star (becomes a Flame Whip) and Gold Dagger with fire.
