But as much the little ponies search the forest, a dragon is not found.  
Finally, they try a dragon call. Because they do not know how a dragon call goes, they try all the calls they know.

Instead of a dragon only a few animals appear for the ponies. “Fluttershy would certainly be happy,” sighed Applejack.  
“Maybe it works with dragon food?” muses Twilight Sparkle. “It is best to ask Spike. He’s probably already at Applejacks Farm, our picnic starts soon so let’s go at once.”

99% of the comics from the fans are better than this and have a way better story. Even if you consider that this is a book for little children.
