Super very cool show.
Love how people say "Stop indoctrinating our children by putting out a kids show where two characters are in a homoromantic relationship". It's not sexualised nor is it "indoctrination". I had anti-LGBTQ propaganda shoved down my throat as a super young child (which was FAR more inappropriate than this) and yet I still turned out trans and gay. By this logic there should be no relationships in kids shows at all otherwise it's indoctrination. Don't try and mold your child into your warped view of what's normal.
Also with "It's satanic" or stuff like that... it's literally a fantasy world where there's little creatures that happen to be demons. What's your kid gonna do? Somehow find and join a cult?
