The Dink Network

I'm in the underground earth knight maze (where I have to blow up the barrels) in order to reach HIM. I've been all over it several times, but can't get ALL the barrels. I see 2 places blocked by rocks that a bomb might cure---is this what I should do? If so, I gotta head out and get somemore. Please advise. P.S. In the walkthrough, it says to KICK the earth knight---can dink do this? and if he can--how?

I'm going to assume this is for FIAT... so I'm moving it there.

I'll give you a hint: arm your fists.
