The "sticky bit" (or "chain bit") is one of the per-sprite attributes stored in the Sprite Control Bank 3 (bit 6).

Setting it to 1 makes the corresponding sprite "stick" to the right of the precedent one.
The GPU will automatically place it 16 pixels to the right of the precedent sprite, use the same Y position, size in tiles and vertical shrinking coefficient. Only the horizontal shrinking coefficient is left independant.
Chained sprites can also be called "driven sprites".
Changing the driving sprite's attributes will change all those of the consecutively chained sprites.
