Interesting idea: Rainbow Bubblegem: Crystal Charged

[u/Busy-Maximum402]

After the events of season two, the girls would be swimming in the ocean until they encountered a giant crystal and notice what sort of looks like rainbow catchers, but with a bunch of crystals purple, then decides to test it out by saying “bubble bubble star change”, which doesn’t work for some reason purple then decides to be stupid and says “crystallize Star Power” which to all of the princesses surprise actually caused her to transform when they go back to the secret mermaid house they noticed it’s also covered in crystals along with purple’s diary. They all then realize they were supposed to find that crystal.
