1. A lost circulation material (LCM) object comprising:
a solid core comprising wood and that is centrally disposed in the LCM object; and
tentacles comprising first tentacles and second tentacles different in material than the first tentacles, the tentacles attached to the solid core and extending from the solid core to entangle with other tentacles of a neighboring LCM object, wherein the first tentacles comprise a greater percentage elongation at break and a lower Young's modulus than the second tentacles, wherein the LCM object is configured to be placed into a wellbore in a subterranean formation to collect solids on the tentacles as entangled to form a flow barrier to cure loss circulation in the wellbore, and 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.
