A suggestion for “Chicken/Partner Acrobatics”: Since CI3U have its “Acrobatics V3” wave (exactly is wave 115 of CI3), how about we can see this in a CIU wave? “Acrobatics V3” can be appeared with 50% appearance as a variant of the current “Partner Acrobatics” direction in CIU.
Better word: Make Henterprise in “Hend Game” boss wave starting from up-side down direction.
