Int. Language Int. Title Translation
Dutch Lol met een lintworm* Fun with a tapeworm
French Gastroboy The guest
German Bauch-Probleme Abdominal problems
Spanish El problema de Tommy Tommy's Problem**

*In Dutch LOL means Fun. It's a actual word and should not be confused with L.O.L. (Laughing Out Loud)

** It is very strange that the Spanish dub of the episode is called Tommy's Problem. Due to the fact that Tommy doesn't have any big problems in this episode and doesn't have a big part in the episode. The Spanish dubbing studio has probably translated the word Tummy to Tommy by mistake.
