I have a Tufo who likes sharks but dislikes fish...
I have a Laka who dislikes potions and her parents are both Master Scientists and were when they bred! Even more ironically, the mother was given the fertility potion right before being bred and having Laka! Laka also dislikes crab meat which is her mother's dislike.
But I love a little girl I have named Tamata. Because she dislikes rain. I know it's not a big deal or even ironic, but I love how all of the other kids go play in the puddles and she runs for cover instead :P
