Samson and his tail biting friend Benny.
Samson is a light elemental leech while Benny is a dark elemental.
Benny notably suffers from Renfield's syndrome, aka obsessive blood drinking. Seems he takes the name LEECH seriously.
Well in order to keep Benny from spazzing Samson lets him have a nibble or two of his tail every so often- and sometimes out of nowhere.
