yeah ninjamites have nothing to do with muscle and were released by a completely different company originally in the US.
here is a thread for them -- http://www.littlerub...hp?showforum=88
but as ive found the uncommon to common they got yellow, red then black being the most common. There arent any "rare" ones in the US line much like the exogini that were released in more colors, and in different colors depending on country.
As to what they are worth:
Black figures usually go from $1-$6
Red figures usually go from $3-$8
but there have been instances where European collectors have paid many times over these prices for the figures, usually unknowing that they aren't popular here in the US.
Most US collectors of different LRG toy lines look down on Ninjamites, since they are kinda blah figures (Sub-par sculpts with bad paint apps), and wouldn't pay more than $.25 -$.50 cents for them.
hope this helps.
