Sleep is the 4th Apple & Onion short. They sing about sleep, and as a result get barely any sleep
- This is the first time where we see Apple's feet without socks or shoes.
- This is not the first time for Onion's feet, which are seen in the Pilot and in 4 on 1.
- This is the second time Hoagie is in a short, even if he doesn't speak this time and isn't directly mentioned.
