Teddy and The HUGE Carrot

Teddy is a chestnut pony who works as an equine assisted therapy pony. When he's not working he embarks on adventures where he meets different characters and makes lots of friends. Whilst on these little escapades he sometimes gets into trouble, other times he learns something about himself, but often he will have so much fun! In his very first story, Teddy finds a really HUGE carrot in his field and he is unable to get over his excitement.
He could literally sing for joy. Where on earth did it come from? Why is it here? But, more importantly, how can he keep it all to himself?
