Season 5, episode 9 of The Magicians is named Cello Squirrel Daffodil. Why is this episode named as such, from what reference is this name taken?
Plover is entrapped within the Poison Room in the Neitherlands. He is infected by little bugs called tongue twisters. When we see him, he is spouting gibberish, and his first words (that we hear) are ... wait for it .... "Cello, Squirrel, Daffodil".
