I'm sure it's been suggested before bbuuttt: ligers!

Tigons are lion mom x tiger dad, where as ligers are lion dad x tiger mom.





In real life Ligers end up looking different to tigons and are much, much bigger, though have the same fertility issues as tigons.

Obviously your lionesses wouldn't be able to give birth to a Liger BUT gen ones they could be obtained from a explore event.

In explore your lion has a chance of comming across an abandoned pet - a female tiger, who you have the option of spending some time with.
Then 8 days later whilst exploring again there's a super rare chance you come across the same tiger and she gives you a cub- the Liger which was the result of your previous... Activities.

Adult Liger females have a chance of passing on the mutation in the same way as current hybrids, but gen ones can only be obtained from the rare followup explore event.

Alternatively if people don't like the explore idea it could be a raffle:

Once a month a female tiger visits lioden and every king has the chance to enter the raffle and 'woo' them!
Whoever wins gets to reverse breed to the tigress and is delivered a Liger cub!
(so everyone has the same chance as the raffle lioness, but instead of weekly, it's only once a month which would keep gen one ligers rare)




Let me know what you think on this idea :D

Also if you don't support please give a reason! I'm curious as to why etc
