Mystewious noises in our woof.‏

Hello evewybody,

We have some mystewious noises in our woof.
Sumtimes it sounds like litta foots wunning fast and today it sounded like litta foots fell down between de walls.
Wot is it?
Bernie twy to smell it but it high up in de woof.
If it is a mousie, den it be a big mousie.
Maybe it be a wat? or a possum?
Bernie twy to get up dere and see wot it is.
Gwand-ma and Gwand-da and Mummy say Bernie should not go up dere cos whatever it is might hurt Bernie.
But Bernie bwave.
Bernie twy to get up dere and den he can tell evewyone wot is de mystewious fing in our woof.
Wish Bernie lucks.
Luv fwom Bernie.
