feeding

SCP-021 appears to feed exclusively on pigments in the host's skin. This can include melanin, in which case the subject appears to be suffering from vitiligo. However, the organism shows a marked preference for other tattoos and will seek out and devour these before resorting to natural pigments. It should be noted that the feeding process itself, beyond the sensation of movement, is painless; normal tattoo ink simply vanishes as it is 'eaten'. The organism maintains a constant size, and no excretions have been observed. The organism is capable of clearing over 0.6 square meters of skin per hour. One may 'feed' SCP-021 by (quickly) tattooing fruits or small animals on the host.
