Apart from regular emojis like ♥️💥🌳, Mastodon servers also support custom emojis like :heart_fire:.
You can find the custom emojis available on your specific server by writing a special URL in a browser. For my instance mastodon.social, the URL I need to write is this one: https://emojos.in/mastodon.social
If you are on another server, just replace the last part with your server name.
Once on the page, you can copy custom emojis onto the clipboard and paste them in a Mastodon post.
