[The male Smeargle comes over, curious, and Neku carefully picks up his tail to show off. Leo doesn't seem to mind. He is getting pets!]
See how it's really long, and fluffs at the end? There's a gland on the end that produces a paint like fluid- yeah it sounds gross but it doesn't smell bad and it's pretty clean. Anyways, they paint things with the tip of the tail. Mark their turf and things like that.
[He carefully turns Leo around to show his back-]
When they are full grown other Smeargle mark their backs with the 'paint' too, to show they're adults.
