First up is this large 5 1/2 inch Uneeda Wishnik Batman troll in his colorfully silkscreened costume. He retains his original, and unusual, bulging plastic eyes, but has lost his cowl and cape, which is typical for this troll.
Next we have a rather uncommon 3 inch troll wearing a one-piece winged cape and cowl. This troll is seldom seen, and it was really exciting to find one.
Conversely, here's the most commonly encountered Batman troll: a 3 incher wearing an odd red costume, perhaps to avoid licensing issues (some people call this a Robin troll, Batman's sidekick, but I don't think it looks like Robin's costume at all):
Lastly, here's my greatest Batman troll find: the Batnik Club Official Emblem, a sticky badge in the shape of a Bat Troll. Check out the highly detailed instructions for use on the back of its package! I haven't removed him yet, but it's awfully tempting...
