The scene changes to Hook Mountain, where Lion-O must beat Tygra at a test of mind power. The Tiger Clan on Thundera were given special mind powers that enable them to produce illusions to their enemies. Lion-O must be able to distinctly separate the real from the unreal. Lion-O is clever enough to see past Tygra's illusions, and is able to earn his Thundercat insignia during day four of his trials. (thetvdb.com)
