In "The Tourist" when Wander realizes he became too competitive and goes back to Ziziks to apologize to Sylvia, a horn is playing an instrumental version of "Wander Over Yonder End Title Theme".
The scene where Hater slow-dances with Entozoa and sings to her is reminiscent of the titular song from Beauty and the Beast (1991).
In "The Tourist", every time Wander shouts "Done!", the exact same recording is used.
Introduces a slightly shortened version of the theme song to make room for commercial time. When it gets to the part where Wander halts Sylvia and points, instead of looking forward, Wander looks upward and points in that direction with a worried expression, followed by a shortened and redone instrumentation to introduce Lord Hater, then it cuts right to the final chorus.
