Cant get rid of frequent emojis, UNICORN.

I have never used a UNICORN emoji that I can remember, yet its always there as a frequently used.

I have reset keyboard. Rebooted Phone.

I have deleted emoji keyboard. Rebooted Phone.

I have reset entire phone.

Frequent F#!*ing UNICORN emojis keep coming back.

I have created and used new emojis sent around twenty new messages with different emojis, but that UNICORN keeps haunting me.....HELP........
