Heres some i found for the tyrannian elephante...
First of all, I looked for things with tusks... and it turned out that they were all tyrannian petpets so that works out well, i guess
Tyrannian Noil
If you want a pet that is one of the main original "petpets"... a noil is the way to go... with the tyrannian twist, of course, because it has the tusks to match, and the yellow on the noil matches the elephantes eyes perfectly..... so they look great together!
Donksaur
If you are looking for a more "original" petpet that most people dont have, a donksaur is a good one. The colors dont match, but its tyrannian, has tusks, and its got a wierd attitude that makes it look like an easy-to-take-care-of petpet.... its odd, but still makes a good petpet.
Tyrannian Snarhook
If you want a "cuter" petpet, this one is definetely cute, and the thing has tusks as well... and its also very hairy, like the tyrannian elephante. Yes.
Woolypappith
If you are looking for a petpet to match the physical charactoristics, this is the best best match. Its... a mammoth... like the tyrannian elephante... the colors dont match, and yet, they look great together!
I also found a couple bird petpets that look decent with the tyrannian elephante....
Brown Pawkeet
If you dont want a tyrannian petpet, this is a basic petpet that matches the colors pretty decent. Its different, but still cute.
Airax
This is a cool match... Airax are cool petpets, and they are a tyrannian bird, and they colors look nice too!
Tyrannian Miamouse
This is another petpet that colors match nicely.. this is an overly cute petpet, and it has big ears, which is nifty. And swell. Yes. Im done now
Hope I helped...
