Here's when the Human Mane 5 encounter the Clawer in Wrath of the Century.
[it is now morning and we now view the Mane Human 5 at the beach]
Human Rarity: [relaxing in the sun] Ah. The sun, I could just tan myself all day.
[AJ (human) & Rainbow (human) are playing volleyball]
Human Rainbow: [hits it]
Human Applejack: Ah'm gonna beat ya! [hits the ball]
Human Rainbow: Hyiah! [hits the ball] We'll see about that.
Human Fluttershy: [looking at animals in tidal pools] You are all so cute.
Human Pinkie: [blowing leaves]
[just then Rarity (human) hears something]
Human Rarity: [lifts her shades up] What's that?
Human Fluttershy: What?
[then something starts heading for them]
Human Applejack: What in tarnation?
[Then out of ground was a hybrid Deceptitrain]
Human Fluttershy: What is that?!
Human Pinkie: It's a Deceptitrain worm!
Clawer: [shows his claws] ROAR!!!!!!
Human Rainbow: Worm, nothing! That's a scorpion!
Human Rarity: No, it's both!
[Then Percy comes in and transforms]
Percy: [deploys his face sheild] Hey you! [fires]
Human Pinkie: GET HIM, PERCY!!!
[The Clawer snaps his claws and swings his stronger around. And fires rockets from his claws]
Percy: [swats each of the rockets with his energy ax and then he hits some spots]
Lady: I'M COMING FOR YOU!!! [jumps off a cliff and transforms]
Human Mane 5: LADY!!
Lady: [deplosy her lightsabers] Come and get some!
[But the Crawler swings his stinger and stungs her]
Percy: [undeploys his face sheild] LADY!!
[The Crawler digs back under the Ground]
Human Rarity: That thing was menacing!
Lady: Don't worry, it's only a stung. [groaning]
Percy: Not without medical attention, we've gotta get to Sparkshot! can you transform back into engine mode?
Lady: Yes. [transforms] I can still live. [puffs away]
Percy: [transforms] Come on, girls. Get dressed in your street clothes, we need to find the others!
