how do I get pass level 55??? what do you do!

can someone tell me how do you solve this level nothing i do works what is the trick?

use the bomb to blow away the snow.

I blew away the snow and before i can get the key its back you only have one bomb and you can't get the key and get the bomb at the same time. where do you put the bomb. why doesn't this game show you how to complete a level if nothing works???!!!

Dig down to the key, go back thru to portal, open the lock.
Same thing for the second lock.
To get the kitty, dig down to it, go back thru the portal
go down to the snow and blow it
the kitty will come to you.
