I remember that show …. the original run and one of the local stations used to run a whole block of filmations stuff in a block it was Blackstar he-man tarzan and zorro and a couple of “funny” other ones would rotate in and out (who ever at MGM thought to give them tom and jerry needs to be castrated and disemboweled in the real and after life)
the episode I remember was they had a flood and the aquaphobic dwarf gnome whatever had to suck it up and save the people and tree they lived in
I remember that show because the Sword was unique (I am pretty sure I even had the toy) but I honestly don’t hear the resemblance in music other than a sight one.
