Freak is easily spooked. Flesh-eating monsters tend to scare him away. So do fireworks, clowns, and the smell of Sadie's weird British Ribena drink. {Can't blame him on that last one. Sadie grew up in London and developed some pretty strange tastes.
Freak is a character who gets easily frightened by various things in his environment. For him, flesh-eating monsters evoke a strong sense of fear, leading him to flee. Other triggers include loud noises like fireworks and the bizarre presence of clowns, all of which make him anxious and prompt him to retreat.
Additionally, Freak is particularly unsettled by the smell of a peculiar British drink called Ribena, which belongs to a character named Sadie. This drink is a reflection of her unique upbringing in London, contributing to the odd tastes she has developed, which Freak understandably finds off-putting.
