Quick summary.
An Odyssey Skyline bred to an Onyx and produced an Odyssey Collision, since we already know Onyx is recessive to Odyssey Collision it has to have come from the Odyssey Skyline. I assume originally from the Birthday girl but that doesn't really matter since its a clear proof that it is recessive to Odyssey Skyline
That just leaves 3 eyes to test against.
