"Bow to the Rainbow"
Liam submits, only for the Monster Rainbow to call Liam a cowardly fool, laugh evilly, and strike him with lightning.
"Destroy the Rainbow with Magic"
"Sing to the Rainbow"
Liam's singing made Monster Rainbow cry due to it being a sad song about a man jumping off a cliff and dying. Unfortunately, this only resulted in it raining again.
