[She can't keep from giggling at how his Torchic seems to perk up at that, and she nods. Her Houndour comes into view - or at least, makes his presence known with a loud howl, and she laughs again, gently pressing her hand against his face to keep him from jumping up on her lap and consequently, the Togepi still seated there.]

Yeah, they are. Each Pokemon has one or two different types and can use all different kinds of attacks. Some of them with the same type and some that aren't at all. Some do damage and others just weaken what they're fighting or strengthen themselves. [She glances down at her Houndour and scratches behind his ear a little.] And certain attack types do more damage against Pokemon of a certain type, like how Fire-types are weak against Water-type attacks. But if a Fire-type attack hits a Water-type Pokemon, it doesn't really hurt them very much.

[She pauses and tilts her head slightly.] Makes sense, right?
