Dreamworks: Sleep & Death
What these two have in common?
Personifications of abstract concepts.
Aren't what they seem at first glance (Death is a huge, scary looking wolf who respects life and Sleep is a muppet-looking creature who suffocates people with pillows)
Likes to drink (bonus: first proper introduction occurs on a table)
Based their physical forms on mammals (Death is a wolf while Sleep is based on an old teddy bear)
That's why they are ✨ fluffy ✨
And that's why when you look at them you want to hug them even if that's not a good idea to begin with
Observe and know mortals, in this case Death observes Puss in all his past deaths and Sleep knows a lot about Orion to recognize him as "the kid who is afraid of everything"
Problably there are more reasons. Waiting for another trailer to give us more information about Sleep.
