Spyro is definitely absolutely going to be exploring the dream realm whenever he isn't on bouncer duty. In fact he's probably going to be really whiny about having to stay in one place to do his job??? Staying in one place when there's exploring to be done is really not his idea of a good time. He might even be tempted to shirk his duties in favor of going to hunt some nightmares! Exploring new lands and fighting enemies are his absolute jam.

The concept of a dream realm really isn't that weird to him either. Where he's from, there's an entire sub-culture of dragons known as the Dream Weavers who literally conjure this kind of nonsense for a living, so he's completely unfazed by the wackiness of this place.

Anyway if you need a nightmare fighting buddy or exploring partner, Spyro's your dude. Also, he's going to be giving Sparx a dream catcher to hold on to, so naps and the like should be a non-issue for him! It may not be immediately visible when Sparx is holding it though because ~dragon magic~, so I'm expecting he'll be getting yelled at plenty for appearing to be sleeping without any kind of dream protection.
