Rideable pigs

[yoraze]

Issue description

• Expected result: You can put a saddle on a pig and sit down.
• Actual result: You cannot do what is described above.

Steps to reproduce the issue

It's not a bug, it's a feature request, but they're missing from your repository - so I decided to take the "Bug report" template.

In a single game, you can ride a pig. It would be good if on your software it was also possible.
