I imagine daddecai would be a super teaser, saying he would eat or smother you if you didn't do your work/training (or whatever he would make them do)
Chores. Always chores. And hey there's probably plenty of them to do around a giant owl's abode. And, plenty of reminders what you could become if you ever empty the bones out of his study dustbin. And if you ever think you can slack off, you have no idea how long and silently an owl can lurk in the shadows, watching.
But hey, if you do well, of course he'll cuddle you up under his wing/against his stomach while watching old movie musicals on television.
Ooooor he might catch you peeking in his old private photo album and clear his throat loudly behind you. And let you stammer out excuses before he admonishes you with a strict lecture about privacy. And then eats you.
