What colour is my heart?

Taken from Sonic the Hedgehog (SatAM), Episode 15 - Sonic Conversion “Snively, what colour is my heart?“ “I don’t see a heart sir.“ “Exactly.“ When I first watched this when I was young, I expected the answer to be “black“. I thought it was nice that Robotnik was actually implying that he had “no heart“ instead. The DVDs for the cartoon can be bought here: =sr_1_1?ie=UTF8&s=dvd&qid=1282315103&sr=8-1
