Arthur watched in awe as the stout creature waddled towards him. Wha… What is it?" he asked merlin, who sighed.
"It's called a penguin. It's a type of bird" he replied. The penguin looked like no bird Arthur had ever seen. He reached out to touch it, but the penguin snapped at his fingers. Merlin rushed over to check his friend was okay, trying to hide his giggles. "it's okay!" he reassured Arthur. "You're not bleeding-or dying" he added as an afterthought, giving a lopsided grin and walking back towards the penguin. "good flippy" he praised, patting the bird on the head and throwing it a small piece of fish. Flippy chirped happily, an evil smirk crossing his beak.
