Creature Malformation

[phi19]

So, I am with manim version 3 feb 2019
I followed this tutorial: https://youtu.be/KGdA8IB6JL0
I changed ALL the "NumberCreature" with "criatura_phi"
I have this code:

class phiCena(Scene):
def construct(self):
Ale=Alex().to_edge(DOWN)
palabras_ale = TextMobject("Learn to do \animations with me!!")
self.add(Ale)

self.play(criatura_phiSays(
Ale, palabras_ale,
bubble_kwargs = {"height" : 4, "width" : 6},
target_mode="speaking"
))

for k in range(0, 4):
self.wait()
self.play(Blink(Ale))

When I render WITHOUT the middle-part (the part surrounded by the ###), it all goes right (the phi_Cena_ok gif).

But when I try to render WITH the middle-part, something weird happens (the phi_Cena_not_ok gif).

(I render it like mp4 video, but I had to convert them to gifs to pu them here :P)

That is because you don't have number_creature_speaking.svg file in your svg folder, you have to create one, all target_mode=""som have to add a new svg file named as number_creature_some.svg.

Wait, what? Sorry, did not understand anything.
Do I have to create a number_creature_speaking.svg on the svg folder? Still doesn't work
Also, what do you mean with " all target_mode=""som " ??
And what I have to do about the thing "have to add a new svg file named as number_creature_some.svg"?
Do I have to make any change in the code?
