Among Neptune's servants are octopuses with 6, 7, or 8 legs. Those with 7 legs always lie, those with 6 or 8 legs always tell the truth.

Four octopuses meet. The blue one says, "Together we have 28 legs."

"Together we have 27 legs," says the green one.

"Together we have 26 legs," says the yellow one.

"Together we have 25 legs," says the red one. How many legs does each octopus have?
