Siamese Balloons are two balloons joined along one wall. You inflate them via two separate nozzels, but if one is burst, then the other one remains intact (although with its deflated twin now hanging limply from one side.

Are they shaped like Chang and Eng?

The bad taste version certainly could be.

Wouldn't there be extra stress where the surface turns a corner sharply near the join? To avoid tearing at the join you would need to use thicker or stronger rubber or material whatever stuff balloons are made from, which will generally compromise the inflability and balloonality of the thing.

We used to inflate balloons inside each other, you nest them deflated and then inflate them starting with the inside-most one. They can end up very beautiful if the balloons are translucent and there is a lot of air gap between layers. If they are opaque you can produce spectcular active displays by layering contrasting colours, making the air gap between balloons small, and rapidly bursting them one skin at a time.
