Reminds me of the ‘Magic Roundabout’ which used animations from a French TV show but completely changed the characters, plot and script. https://en.wikipedia.org/wiki/The_Magic_Roundabout
Reminds me a bit of other overdubs that went the whole rescript route, although in comedy form:
''Most eXtreme elimination Challenge''

or the 1960s motion picture ''What's Up Tiger Lily?''
