Lead jelly Hailey to the shop keeper for one, then it will leave a body behind. Then lead the orange zombie from the right of the map to the left body to get 2 animations. Wait until cum to see the color change. As for the blank space below Heather and the last blank space in the jelly section, I have no clue.
if you mean the animation next to the girl with green hair then it's a secret one firs do exactly what lags did in minute 7:40 after that complete the objective then return to Mason sister standing near the shopkeeper talk to her till she says " I'm going there " then fly back to Mason and you will find it talk to them and it will be unlocked for you
