that's my answer

Just a thought.

Quite straight forward: "...experts on musing games". I believe "parlor games" does not fit the context.

Maybe this would work:

The film is a surreal little twist on a Disney cartoon, celebrating the magical absurdity of life.
PETER FISCHLI and DAVID WEISS. PARTS OF A FILM WITH RAT AND BEAR
http://www.fondazionenicolatrussardi.com/incursions/parts_of...

would be my choice as it is close to the idea of something that puzzles and involves deep thought (often a paradox) see def.2 of Collins and the Spanish term means deep puzzling thought

Conundrum...
A paradoxical, insoluble, or difficult problem; a dilemma:
conundrum (kəˈnʌndrəm)
n
1. a riddle, esp one whose answer makes a play on words
2. a puzzling question or problem
[C16: of unknown origin]
Collins English Dictionary

here is a reference to their work as being full of conundrums

The Swiss duo Peter Fischli and David Weiss pursued in their art what they called “the pleasure of misuse.” Everyday objects, freed from their intended use, could suddenly acquire an eccentric beauty or a new meaning. A major retrospective of their influential work is full of humorous conundrums, such as: “Is it true that traces of aliens have been found in yogurt?”

Throughout the course of their partnership, Fischli and Weiss probed the idea of dualistic thinking. Perhaps because they were a team of two involved in constant dialogue and debate, they consistently interrogated Western culture's reliance on contraries. In one way or another, everything they produced together playfully unravels what the artists understood to be 'popular opposites'-labor versus leisure, fiction versus reality, kitsch versus beauty, and the banal versus the sublime. Through their sustained investigation into the everyday, Fischli and Weiss undid false dichotomies with the conviction that bewilderment might be a desirable state. The artists embodied this approach in their alter egos, Rat and Bear - See more at: http://www.noodls.com/view/4F775F998B31C229BD190F92E8DB852D2...
