Feral Changes

Out of the five Mystery Kids who've been turned into werewolves, Norman would be the most ferocious looking...Damn! O_O

This is basically showing more on the transformation, normally there quite painful but on a full moon they are unbearable! For example the gums around the teeth would bleed due to the teeth changing shape, the bones would rearrange and muscles would expand causing the clothing to tear. Lets not forget how their animal instincts would increase in strength each night with the full moon making the instincts twice as strong than the other nights.

Of course there's a good chance after they change into their werewolf forms, they would revert into a more feral (and more bloodthirsty) state with some difficulty recognizing people such as their loved ones and would either attack them or just run off to look for prey else where. In Norman's case, he probably wouldn't want to show himself to the others after what happened that night but then again neither would the others.
