ISBN: 978-0-76155-713-5.</ref> are clusters of interactable objects in ''[[Super Mario Galaxy]]'' and ''[[Super Mario Galaxy 2]]''. A stone circle consists of eight small rocks arranged into a ring on the ground. [[Spin]]ning within the ring transforms each of the rocks into a collectible [[Star Bit]]. There are iterations of circles themed to the [[level]]'s environment. In beach [[galaxy|galaxies]], such as the [[Beach Bowl Galaxy]] and [[Cosmic Cove Galaxy]], the player can find '''shell circles'''<ref>Black, Fletcher. ''Super Mario Galaxy: PRIMA Official Game Guide (Collector's Edition)''. Roseville: Prima Games, 2007. Page 229.</ref> (or '''shell rings''').<ref>Black, Fletcher. ''Super Mario Galaxy: PRIMA Official Game Guide (Collector's Edition)''. Roseville: Prima Games, 2007. Page 257.</ref> The cake-shaped planet at the end of [[Sweet Sweet Galaxy]] has a '''strawberry circle'''<ref>''Super Mario Galaxy'' internal filename (<tt>ObjectData/CircleStrawberry.arc</tt>)</ref> on its top. On an [[airship]] in [[Bowser Jr.'s Airship Armada]], a circle is combined with a [[valve]], where spinning it releases Star Bits from the eight vents surrounding it. Only the stone and shell circles appear in both ''Super Mario Galaxy'' games.

There are [[Flower (Super Mario Sunshine)|flowers]] in ''[[Super Mario Sunshine]]'' that are similar in concept, with flowers growing in rings, and they release many collectible [[coin]]s when sprayed all at once.
