Happiness is Marineland
Before moving to their 'inevitable' Everyone Loves Marineland! commercials, Marineland had a commercial where the walrus king asked 'Happiness is..' and the children would respond, culminating in the former catchphrase, 'Happiness is Marineland'. However, it is possible that the commercial had other dubs, so the Chez Creson was in one of them. However, no Marineland commercials have surfaced in a non-English language.
Two lost commercials
A playlist on YouTube lists Marineland Commercials over the years. This includes two from 1988 which have since been deleted due to copyright, and have not been archived via Wayback. However, it is possible that before the takedown, one of the two commercials could have hosted this speech from the walrus. Until it resurfaces, this is yet another lost commercial.
