err...better not eat so much carrots.
coz the other time bear ate too much (for consecutive 3 days),
the white white part of the eye turn slightly yellow/orange.
Once i took carrot apple juice for 4 days, my palm turned slight
orange/yeliow too >_<
that's because of the overdose of beta carotene. quite harmless.

but i think the udon just enjoys being orange.
