Omnomnom.
Edric was just sitting on one of the benches at the topiary garden, minding his own business and having some peanuts. He was quickly regretting his snack choice, though, as the saltiness of it began to make him rather thirsty.

But still, there was no getting Edric off that bench, not even the need for water. He was tired and the place was comfortably isolated from most of Hogwarts's population. It was the perfect spot to relax. Until, suddenly, something green snatched the bag of peanuts straight out of the Gryffindor's hand.

Turning in the direction of the thief, Edric's expression transformed from one of surprise to one of 'you've-got-to-be-kidding-me'. The giant, elephant-shaped bush stood by the bench holding Edric's snack with its trunk. The creature then turned the bag over and emptied the contents in its mouth.

Edric just watched with disbelief.
His lunch had been stolen and eaten by a plant.
A plant.
