I used to think the show was great for my kids. Until I came across an episode with an unsettling character named "Gooble". The character seems very ill-fitted & unsettling compared to the rest of the characters. It always frightens my children & they now dislike the show. I really would like to know the true intentions behind that character. The rest of the seasons seems dark & ill-fitting as well. Not a satisfied parent.
