Dot and Bubble Trivia Quiz

Answer: Lindy

Lindy Pepper-Bean is a self absorbed rich girl who literally spends most of her time in a social media bubble. Cooper and Natalie are her friends, while Penny is her mother.

Lindy was played by Callie Cooke. She has been acting in British television since 2016. Her credits include "Cheaters" (2022), "Wedding Season" (2022) and "Henpocalypse!" (2023). Callie is from Leicestershire. Huge props to Callie for taking a really thankless role of an obnoxious character and making you care about her.

Susan Twist makes yet another appearance, this time as Lindy's mother Penny. She is a victim of the monster attack on the home world. In this episode, both the Doctor and Ruby commented on seeing Twist before.

"Itsy Bitsy Teeny Weenie Yellow Polka Dot Bikini" was first released by Brian Hyland in the summer of 1960. It was a #1 hit in the United States, and translations were #1 in France and Germany.

Lindy sings the song twice, first to block out the Doctor and later when she is nervous.

Given the plot, "Purple People Eater" might have been more appropriate.
