Winnie the Pooh is a great theme for a cake or for a party in general because it's applicable for both genders. Boys and girls both love Pooh and his friends. Moreover, the theme is suitable for people of all ages, not just toddlers and kids. Pooh and his friends have been around imparting lessons and embarking on adventures for years. And even if the TV show has stopped airing and it's been a while since the last animated film, children still know Pooh and his friends because there's a whole bunch of Pooh merchandise, including toys, that they wouldn't miss.
