Mr Arthur, Miss Echo and the Grumpy Toad

Mr. Arthur is fed up with Miss Echo,
A puppy who is causing mischief and mayhem!
He can't keep up with her antics as he tries to keep her out of trouble.
She flies from one disaster to another with him on her tail!
But has she gone too far?
The Grumpy Toad thinks so - she's pulling his home out of the pond!
What does he have in store for her?
And who else has moved into the house to cause mischief?
Can the dogs unite to keep the peace in their home?
