[Levels] Im Stuck

I need courier cat to get past river stinks but i cant beat this red duck thing. Its just too strong. Apple doesnt do much, can can get 1 hitted i think and my island and crazed whale dont do anything. White garu and phonoa dont work either and dark gao and mitama are anti traitless. Those ubers are all lvl 19 except gao is lvl 20 and mitama lvl 17. My loadout is pretty good i think. I tried gato amigo, crazed wall, pirate,can can, paragon, fried shrimp, phonoa, mitama, garu and gao. I also tried gato amigo, crazed wall, pirat, crazed whale, island, fried shrimp, and all the previous fest ubers. None worked. The first one got him to 89%. The second to 92%. Its too difficult. How do i beat ashvini desert lvl two or lvl 4 of hidden gapra forest???
