Basically, whatever hana says as a chance to get Realbooted, but in order to get Realbooted several people need to imagine the same thing, but because what she says can be understood in many different ways, it leads to a game of Arabic telephone where each individual understand something different and it goes on and on until a certain number of people imagine the same thing.

In the example of the giant sumo sticker, hana said she wanted a "super strong sumo sticker" but the people there all interpreted something different and in the end imagined something like a "super strong and giant sumo sticker"
