As stated in game, Taffy is an inorganic creature with cotton inside and resembles a bear and rabbit, with its ears neither long nor short, with brown fur and two black eyes made of glass beads. His eyes shines brightly and are able to cry water droplets.
In his human form, Taffy appearance diverge from his normal form, he is blonde with light peach skin and blue eyes. Taffy looks young and his outfit resembled those of Hinomoto.
Taffy was a normal stuffed animal given to Randy by his parents when he was little. Randy gave Taffy life with magic and made Taffy's birthday the same as his.
Taffy appeared in-game for the first time in Randy March's main route. Taffy was crying because he had a little rip in his fabric, making his cotton falls off a little. Liz (MC) found him and helped knitting it back, to which Taffy answered it didn't hurt, but felt like tickles.
In the event slot "Lively Little Friends", Randy returns to school and Liz finds herself being hugged by a stranger and later she realizes that it's Taffy. Randy explains he created a device that could transform Taffy in human. This Taffy, unlike his stuffed-self, can talk properly. He unknowingly flirts a little with Liz and even kisses her in the cheek. Randy gets so jealous that he returns him to a stuffed animal and admits his jealousy to Liz, which she finds adorable.
Childish, crybaby, but with a big heart, Taffy would do anything to help his "Master".
In Joel Crawford's route Taffy had magic abilities to sense fairies and become invisible. Those abilities were given to him by Randy.
- In Joel's route it's mentioned that Taffy may have a soul despite being inorganic.
- In the star collection event Love in the Air, it was implied that Taffy had a "girlfriend". This included limited avatar items with it.
- In Randy's Event Slot, "Lively Little Friends", Taffy's human sprite came from Solmare's Mononoke Kiss game, from the character Raizo.
Most Taffy Avatar Items are only available for a limited period in events.
