Oops, when building the Support tool to label pet appearances, I didn't realize that there's also a boolean `labeled` field that needs to be true for labeled appearances. Without it, the old app shows the appearance as "Unlabeled".
I also ran this query to fix the rows we'd incorrectly written:
```
mysql> UPDATE pet_states SET labeled = 1 WHERE mood_id IS NOT NULL;
Query OK, 158 rows affected (0.14 sec)
Rows matched: 19640 Changed: 158 Warnings: 0
```
