Sparadrap

Mediocre at best architecturally, the pirates are obliged to reinforce their constructions with sparadraps. The wooden sparadraps are very fragile but the metal ones will only yield to an explosive.

There are lighter versions of Sparadraps that can be destroyed with an energy sphere

Sparadraps (known as Blockades in Rayman DS) are breakable objects found in Rayman 2: The Great Escape, which are used by the Robo-Pirates to keep doors and places of storage locked in their strongholds, and also as a way of fixing broken pipes. The Robo-Pirates have been such poor constructors when building their buildings that they may have forgotten how to break them. There are two types of sparadrap - the wooden type, which is less common and can easily be broken by Rayman's shots; and the metal type, which can only be destroyed by throwing kegs at them.

The name 'sparadrap' is the French word for 'plaster', since they resemble plasters and similar bandages.
