If there was one thing that Peter Pettigrew was proud of, it was his ability to store food almost anywhere on his body. He was a growing lad and he was constantly hungry which definitely helped him to come up with excuses for food. He soon realised that his friends were much taller than him and weren't eating as much but at that point, he just openly admitted that he enjoyed food.
His powers of openly hiding food were always used by his friends and now, sitting in the Greenhouses in Hogwarts, with the Professor going on and on, Sirius turned to Peter and waited patiently for the picnic to begin.
It was similar to a muggle magician's magic act. He pulled pasta contained in pots from the bag that also held his supplies, and he removed apples from the outside compartments. He even had some chocolate bars in hidden in a pile of his parchments.
It was amazing! And definitely better when the two friends dug straight into their feast during class with nobody aware.
