I kind of dig the design.
I just looked into it a bit more and I find it so funny that the EU kept trying to insist the guy was not training Yoda on Dagobah. One retcon tried to claim it was just another swamp planet.
Yeah, and for what? ‘Cause Lucas really didn’t want Yoda to have been to Dagobah prior to the events of ROTS. Nevermind that the film never states as such; Lucas’ authorial intent is sacrosanct (except when it comes to the existence of Sith post-ROTJ. lawl)
