I took a video of Thistle to show how movable quills really are on a hedgehog.

So pictures of Sonic’s quills like this

And even Shadow’s one idle animation is pretty accurate to real hedgehog spines.

Spines are also built to stay in a hedgehogs body unlike porcupines which can detach. A hedgehog spine is so strong you can pick up a hedgehog by single spine and it won’t detach. A single spine can also withstand and bend against up to 200 times the force that would crush it. One scientist noted that he’d never seen a hedgehog with a broken or dulled quill. (Hedgehog quills can be cut from law mowers or hedge trimmers so always be careful and aware if you live near wild hedgehogs.)

While spines are used against predators they are also used for shock absorption. When a hedgehog is completely curled up their spines will absorb incredible amounts for force from falls from trees or high areas.

One study showed, “quills protected from a fall at 15m/s. Despite the velocity at impact, the animal survives unscathed due to the shock absorbing capabilities of its spines, which buckle under the load.” Because of this people have been studying hedgehog spines to better make helmets to protect people from concussions and head injuries.

Sonic’s drop dash could protect Sonic from large falls. (Too bad he mostly lands on his face lol)

One scientific paper I recently read did a study on the durability of hedgehog quills against repeated high velocity impact blows. It concluded that while low humidity quills were better at absorbing shock repeated impact blows weakened the durability and broke the brittle quills. While more humid quills absorbed less shock but remained more durable and survived the repeated impacts with less damage. They said more tests would have to be done because most people only studied the strength of one quill and not all the quills working together like theirs did but that their test may not be entirely accurate since they could not fully replicate the hedgehog’s skin/muscles working with the spines against the blows. As hedgehog’s bulbed tipped quills protect their skin from being stabbed them after falls or hits.

But the results concluded that, “in certain conditions, Hedgehog spines can absorb as much, if not more, than industry standard impact-absorbing foam.”

Just makes me wonder how strong Sonic’s quills are as he uses his to break robots at high speeds. But him using his quills to protect himself while also using them to attack is pretty smart.

Penny Rose: Babbles in Baby

All of tumblr collectively at my husband:

Husband: you don’t even have to understand taxes yet! I can explain them but you’ve got several years before that’s relevant!

Penny Rose: wide eyes, staring at her father, almost intrigued

THE MAN THE MYTH THE LEGEND

Husband: Now Penny there is a lot of misinformation out there in the world and I hate to tell you this but the moon is in fact not made of cheese. That is a conspiracy theory pushed by Big Dairy.

Miguel is right. The first time I watched it, I expected a later scene where Miguel was proven wrong or shown the error of his ways—one where it’s firmly established that adults might make rules that don’t make sense, but they have their reasons and it’s best to abide by their wishes.

But no. That doesn’t happen. Instead, we see that Imelda’s insistence on the music ban, and her refusal to reconsider, indirectly (or perhaps directly) land Miguel in even greater danger, as he wouldn’t have gone after de la Cruz were it not for Imelda insisting he give up music forever. The happy ending comes not when Miguel agrees to give up music to please his family, but when he defies the ban to save Héctor and restore Mama Coco’s memories.
