Anna&8217;s in trouble &8211; she&8217;s doing badly at school & her parents think she&8217;s spending too much time with her pony, Acorn. They say that if her grades don&8217;t improve then they&8217;ll take Acorn away! The Pony Pals are devastated! Can Anna face up to her problems & ensure Acorn really is a pony for keeps?
