Warp Block

The Warp Block is a block in Mario & Luigi: Partners in Time. When Mario and Luigi's (or Baby Mario and Baby Luigi's) younger or older selves are away, and are too far so they can gt to them, if Mario or Luigi press a Warp Block a Warp Pipe will appear and shoot their companions out.

Sometimes there might not be a Warp Block near so they have to find their older or younger selves by themselves.
