Negaigoto wo tanzaku ni kaite.
July 7th is Tanabata. Legend has it that two lovers enjoyed each others' company so much that they never worked. The angry gods separated them with a wide river. Once a year, a flock of birds form a bridge so they may cross the river to see each other, but being a bridge of birds, it can only be crossed when skies are clear. The river is the Milky Way, and the lovers are Vega and Altair. If you write your wish on a strip of paper and hang it on bamboo, and the skies are clear, your wish will come true.
So this is what the Pumpkin Princess wrote on her strip of paper.
For the non-Japanese literate, she wants to be Cure Peach, the previously mentioned girl superhero.
I should probably mention that half the girls in her class wanted to be Pretty Cure. And that the Pumpkin Princess apparently got into an argument with a girl in her class over who would be Cure Peach.
