This set comes in both wood mount and clear mount. If you have it in clear mount, you could mount your monsters on a large clear mount block all at once, ink and stamp in one go as I have done here. You can then position the other stamps for eyes and mouths on the stamped images, press your block over it to allow the stamps to cling to your block, ink, then stamp. The only one I had to repeat was the eye for the middle monster as the image was a single eye and not a pair.
