The Dink Network

I am having a doubt
how to destroy the 3 barrels I see on the small island in south
If I throw axe I break only one barrel,and lose the axe

please help

You'd better keep a walkthrough at hand, because this Dmod is pretty impossible if you don't use one. One mistake and you're bound to having to restart the game.

There was a secret passage somewhere to get to that island of barrels, if my memory serves me correctly... I forgot where, sorry.

you can go down a screen to their left and shoot right, get all three
