this sounds simple, but may be bugged- here is how i did it;
-start a single player game
-pause the game and press square + triangle + L1 + R1 at the same time to open the admin command
-type gmsummon "toad_character_bp_c"1 into the bar then press admin command and unpause
-pause the game and type gfi armor_toad 1 1 0 press admin command and unpause
-press triangle to ride the toad after equipping the saddle, pause and type addexperience 10000000 0 1 press admin command and unpause
-press square to open dino menu, spend all of the points and the trophy should unlock after the last point.
if, like me, your trophy doesn't unlock at this point, here is how i "fixed" it
-pause the game and type playercommand Ascend1 press admin command
this will also give you "Gamma Ascension"
-skip the credits by pressing End
-go back into the single player game
-repeat the first set of steps.
after doing this is i had 88 dino points to spend instead of the initial 73.
