Reposting Sarahs pedigrees as this one is reliant upon the previous one
So first one shows a Special Baby with Soul Sparkle passing Odyssey Tapestry No.1, this showed the eye was recessive to Soul Sparkle and at this point potentially dominant to Crystal Crush. Sarah was intending to check as theres Grey Matter in her Crystal Crush line
In this pedigree we can see the same Soul Sparkle showing special baby had a baby showing Magic Forest, since we know it hides Odyssey Tapestry No.1 we can conclude the Magic Forest baby must hide the Odyssey Tapestry No.1 as it can't hide Soul Sparkle. This also means Sarahs Odyssey Tapestry No.1 baby doesn't hide Crystal Crush but more likely the Grey Matter she suspects hides, but until she pulls the hid on the either the Ody Tap or its Crystal Crush parent we won't know for sure what hides.
