To get this trophy you must first unlock the spin upgrade from defeating Dr N.Trophy, that allows you to repeatedly press Circle in order to maintain a longer spin or slow down your descent from a jump/drop.
Then you must go to the laptop on the large monitor, on the left of Tiny Tiger's (/the first) area and follow the prompts to enable the use of Coco. Then be sure to press R2 in order to swap to Coco if it has not done it, itself.
Once these two steps are complete simply load up a level (be sure to pick a level where you simply progress on foot - you don't want a chaser/swimming/flying/etc level). So to make it nice and easy I chose the very first level.
Then to be sure the trophy unlocks I found it safer to spam Circle before confronting the enemy, waiting a second or two into the spin (as it lasts about 4/5 seconds) then proceeding forward into the enemy to defeat them. I think I didn't get it until about the 6th enemy so I probably wasn't doing it safe enough as I was a tad impatient but there's more than enough enemies to suffice and the hardest bit of this trophy is getting up to the part in the story-line where you have this ability (I believe he is the 3rd boss)
Hope this helps
