1. A lost circulation material (LCM) pill to cure loss circulation in a wellbore in a subterranean formation, the LCM pill comprising:
LCM objects, wherein each LCM object of the LCM objects comprises:
a solid core that is a centrally-disposed and comprises wood; and
tentacles attached to and extending from the solid core, the tentacles comprising first tentacles and second tentacles different in material than the first tentacles, wherein the first tentacles comprise a greater percentage elongation at break and a lower Young's modulus than the second tentacles;
fluid to convey the LCM objects; and
solids to be collected on the tentacles as entangled between the LCM objects in application to form a flow barrier, wherein the first tentacles and the second tentacles are configured to provide a synergy in forming the flow barrier because of the first tentacles comprising a greater percentage elongation at break and a lower Young's modulus than the second tentacles.
