The Battle for Dream Island BFDI has a vast array of vibrant characters, one of which is Gelatin. This charming, gelatinous character is typically seen as carefree and jovial, but there are instances where we see Gelatin's sad side, adding depth to his character and the series as a whole. Gelatin's sadness in Battle for Dream Island helps to humanize him and create a deeper bond. A fanart Battle for Dream Island Gelatin sticker with Gelatin Sad.
