In the park, the mammoth has collapsed again. This time, though, there's someone to help.

Susan is already hard at work treating the mammoth. The biggest problem she faces now is cleaning up her wounds. The mammoth has a large gash across her right shoulder. Within it is the source of the wound: a flint spear head.

Susan has never treated a mammoth, but she has treated elephants, which aren't too different. One big difference, though, is how much fat they have. In mammoths, it's an amazing three inches.

Susan removes the spearhead, then places antibiotics in the wound. She's reluctant to seal it, though.

"Don't stitch it up, it'll heal over, she'll just have a scar."

Nigel is busy watching this is his den.

"As much as I want to help Susan with this, this isn't my field. Still, Susan is the best there is, so the mammoth is probably going to recover. I've already decided on her name: Martha."

-

Eventually, Susan is able to fix Martha's wounds. Once that is handled, Prehistoric Park has to deal with a different issue. One that is, fortunately, much easier to solve.

It's feeding time.

Around the park, residents are digging into their food. Chief among them are the newest residents: the cave bear, who needs to make up lost calories from hibernation, and the wooly rhinos, who had been pushed to the brink of exhaustion searching for food. Everyone is enjoying their meals.

Everyone, except Martha.

Nigel has travelled to Mammoth Mount to assess the issue. It is a small hill between the savannah the elephants live on and the park's tundra.

Here, Martha lives all on her own. And she isn't eating. Nigel has no idea why.

"I don't get it. She should be starving, but she hasn't touched the grass. This is not a good thing. If she doesn't eat, she won't recover from her injuries."

For Nigel, this isn't an easily solved problem.

" I can't figure out why she isn't eating. Maybe the grass is different from what she's used to?"

Nigel's already formulating a plan to solve this problem when Bob radios in.

"Nigel, come to T. rex Hill! There's something you need to see!"

-

At T. rex Hill, something important is indeed going on.

"Bob, what happened?"

"I found the alverezsaur. Problem is, he's in there and I can't get him out."

Sure enough, the maroon dinosaur is within T. rex Hill's fences.

And he's right next to a sleeping Terence.

All of the rexes are napping after their lunch. This makes them safe to approach, but it makes rescuing the rather vocal alverezsaur without waking up the tyrants very difficultt.

"Oh dear. Bob, do you have any bait?"

"Yes, Nigel, but we need to get his attention before any of the -"

Bob's reply is cut off by a high pitched chirp with the fences of T. rex Hill.

Nigel and Bob turn and find that the source of the sound is the alverezsaur.

Who's chirping at Terence.

Who has woken up.

Nigel and Bob can only stare in horror as the giant carnivore opens his mouth upon catching sight of the tiny, furry dinosaur in front of him, which promptly begins... pecking between his teeth?

Nigel and Bob can now only stare in confusion as the giant dinosaur allows it's smaller cousin to peck at its mouth. For Nigel, though, it doesn't take long to figure out why.

"Now I get it. In Africa, birds known as plovers clean the teeth of crocodiles after meals. These guys must do the same for tyrannosaurs. He must have been looking for mouths to clean. It's okay Bob, he's safe from harm."

It looks like this crisis has been averted.

The tid-bit with the wooly rhinos collapsing after trying to dig-out grass is a shout-out to Ice Age Giants, where that exact scene actually happens.
