need blood

Blood? whats that?
Apparently BLM needs some of it.
He disappear for 45mins and came back with a cup of milo and kong guan biscuits.
and look pale the whole day.
(must have been the kong guan)

i wonder if he can replace that with grease which i have plenty of.
in case it doesn't, any one out there kind enough to donate your blood to him?
