When told they can't do 'What's That Spell?' the kids suggest the following alternatives:
Octavia Gale: The Book of Sultan & The Old Stand (She got cut off, so it might actually be 'The Old Stand Back').
Kelemon Ceinfarfog: 12 Angry Dalmatians & 7 Brides for 7 Dwarves.
David Ryan Little: Cruella de Vil on Trial, Jafar in Tights, The Evil Queen, & My Fair Lady and The Tramp.
One can assume that 'The Old Stand' doesn't have a villain, that the villain isn't one of the core four's parents, or that it isn't based on a true story based solely on the fact that Octavia said 'I hate to say it but we have to play it safe' before suggesting it.
Kelemon didn't seem happy with any of the given options.
