So they forgot to include the muscle that lets porcupines not hurt each other and just gave it spikes sounds about right.
It’s science who cares as long as it gets results
“itsa diwema.”
Oh this is a genius idea!
They get hurties because you’re a bad fluffy.
Hedgehogs dillema lol
Pop a few more foals on them spikes, maybe that’ll fix it!
Just wait till it wants babbehs…
Ow 
“Forgot”?
Listen forgot makes more sense after all you want the kids to not get hurt hugging a fluffy after all.
I do like the idea though they forgot to include it so instead of never being able to raise the quills in self defense it cannot put them down.
Forms a symbiotic relationship with the shrike fluff.
It might be an attempt at a fluffifix. Given the number of stories about various genetic abominations to eliminate the fluffy genetic abominations, this one seems comparatively well considered.
Even with the child hugging incidents.
Silly fluffy, you don’t hug with your back! You gotta use your fluffy belly for hugs!
That is their belly. They came out extra wrong.

Poor guy. He hasn’t got much time left.
