Pi Pi and Di Di's One Day Trip In Home

Pi Pi and Di Di is the fastest go home.
They only walk for one hour.
One of the reason is Di Di always hide and I tired to search him.
I have many homework to do that time, 
but Di Di hide and I scared that I will missing him again, 
so every time he hide, I must know where do he hide.
So I am tired to search him.
So I put him back to his aquarium early.
Secondly, I am too busy with my homework, 
so put back them early and I will not scared that they will disappear.
Di Di really like to hide.
He never done this before he lost that time.
He usually hide under a sofa and sleep.
But now everywhere is also his hiding place.
So naughty of him.
