There's only one thing in his mind - the dragonfly he's following through the thick jungle foliage today. As children can do, he disregards all the rest. For example, he doesn't remind himself to dim the brightness of his wings to non-existent, he doesn't look where he's going (he's still in Tephra, he knows by smell, so why bother further than that) and he's never met anyone who is playful like himself - thus far, if he met someone in one of these chasing games, they sidestepped with a snort and ignored him.
A collision with Osiriis could therefore not be helped.
The perlino with his sunlight wings only hears the black-and-vermillion boy when he shouts, but by then it is far too late for either to jump aside - the boy in front of him attempts a stop that Toivo notices is not helpful, but his last-millisecond noticing is not saving him at all. The black two-year old's hind now approaches Toivo, who only has so much time to squeal and duck his head sideways - but his back and hind still catch the other, and they go down tumbling in a frivolous display of legs entangled.
Crashing into the bushes, Toivo might call himself lucky that his wings are made of light alone - warm and bright, sure, but they'll never damage or set anything aflame. Still, he lost his newest friend, and this guy better make up for it! ... if they can get un-tangled that is.
Sides heaving, the perlino and sunlight boy snorts, then bursts into a laugh. "You watch out yourself, you."
He giggles and shakes his head, but when he tries to move, he finds his hind legs under the other, and his front legs only gain footing in the softness of the other boy's side - which is to say, not enough to get up.
