It's a weird story/ Pointless Contest!

The first thing you notice when you enter the building is the glowing orbs. Hovering in the middle of the hallway every few feet, they shine a brilliant white, guiding you along the path. Mesmerized, you walk from one light to the next, following the twists and bends, turning arbitrarily when the orbs go to ways.
But soon you come to a place with no orbs. You run, trying again to find guiding light, when you glimpse it, passing through a parallel hallway. A pink creature, shaped like a blob with eyes. You turn the other way and run back, only to find another, this one blue, coming right for you. You try another hallway, this one with orbs, and an orange being, just the same as the last two blocks this, your last escape. But suddenly, everything changes. All the ghosts(They look a bit like ghosts) turn dark blue and their eyes turn white. They begin to move in a frenzy, their monstrous, bulbous bodies fleeing something, walking right past you, through you. You're safe.
Relieved, you walk down the hallway towards some faraway orbs, but see them blink out before your eyes. Something is eating them. In the darkness you can barely make it out, but it's bigger than any of the ghosts. One ghost, not fast enough, gets eaten by the montrous atrocity, a huge, yellow beast with nothing but a mouth. It devours the pour thing in a single bite, leaving only it's eyes behind. It's coming for you now. You can't escape it. You can see it clearly now, a huge yellow sphere with no features but a gaping hole for a mouth. Somehow it's simplicity makes it scarier than any detailed beast.
Desperate, you reach around on the floor and find, to your surprise, three cherries attached by their stem. With no other option, you throw them into the beast's mouth. As it swallows it disappears- moved on, you suppose, to a new room with new orbs, ghosts, and fruits.
