When people suggest these animals disappear it implies they somehow disappearing a paranormal sense of mystique. Yet, these things have been observed hiding behind trees or burying themselves under leaves or other forest debris. It is speculated this technique is executed extremely fast and is something they rehearse or continuously do all their lives. They will often disappear out of sight behind a tree then change directions moving oppositely where we humans logically expect them to re-appear again and they appear lost from sight. They will often disappear out of sight behind in a technique called, “Walking up a tree,” where the animal climbs a tree swiftly and stealthily without detection.
