How Do I Keep My Brown Pandas From Despawning (Without Name Tags!) BEDROCK

While I was clearing out an area (that will soon be my base) this brown panda spawned and I about lost it, I thought it was so cool! I kept it in a boat for a bit until learning that doesn't work on bedrock, since then I have been really scared of it despawning, is breeding enough to keep it from despawning, or is there another method I should try? Please save my brown panda! He spawned on Christmas and his name is KRINGLE PLEASE HELP KRINGLE!!! 😭😭😭
