PAIN

This can be done on any map (Fail Village, Freeplay With Explosives, Fun With Explosives). This run is in Freeplay With Explosives.

By "ice blocks," they mean the ice on the pond in the center of the map. In the Explosives maps, there are 7 barrels stuck in the pond ice. Explode all of them (which breaks all the ice) in a single run to get the trophy.

If you're doing this in Fail Village, for six sections you'll just need to ooch around the pond. The ice breaks after you stay on it for a few seconds, just be careful not to fall in! To break the ice under the goalie, first you need to throw bomb him with a red present (thanks to thepatcat for the tip).

Here is a video of this done in Freeplay With Explosives:
