Ahh, the slime. I picked up these magnets as part of a magnet and paper diorama in Japan, but opted just for the magnets on my home refrigerator. Look at the grins on their plastic pixellated mugs. And you've got to love the ole 5-pixel highlight.
The slime is my favourite enemy and probably the most instantly regognisable character from the DragonQuest series. I like their simplicity and perpetual slimy happiness.
