A small statue monster carved into the shape of a Ducken. It starts out with a rounded, boulder shape but is redesigned over time to be more square, which fits its name better.
Its name implies that it was carved from a block of stone. Its Japanese name is Burokkun (ブロックン).
|Monster Rancher 2||"This monster's duck-like shape is made up of several rocks."|
|Monster Rancher 4||"Its entire body is made of stone, so no attack can harm it. Only its protruding eyes are vulnerable, but sometimes it steps on them and thrashes around in pain."|

|Monster Rancher DS||"Blocken's entire body is made of stone, making it impervious to most attacks. The eyes are its only weak spot, which it protects well. But it sometimes pokes them accidentally and freaks out."|
|My Monster Rancher||"The form of Ducken is captured here in a few simple blocks. Small parts of it are made of iron sand. It seems so much like a statue that when it moves it can startle people."|
