Expansion idea!!

Hello sims, I doubt you will answer me but I have an idea that for me is quite promising and interesting, which consists of adding hybrids to the sims, for example: A shark and a mouse, that would greatly improve the gameplay and with that the children see it and have the feeling of being dizzy which the hybrids cause when being near them with the description of "is it an (Animal) or is it an (animal)?" And for example if it has the shark hybrid trait it likes to be in the water and since it has the mouse trait it likes to eat grilled cheese bread and with this a world called animal valley is added which is full of hybrids and a library where there are books about them and a secret world, I am not saying that they add all the animals only the ones they want, if they read this, thank you! And sorry for so much text, goodbye!
