As for the original Spyro 2 speedrun, there is a category called "stand on 10 portals" and I think it's possible on Spyro Reignited Trilogy too. I've tried and managed to stand on Colossus's, Hurricos's, Sunny Beach's, Fracture Hills's, Icy Speedway's, Skelos Badlands's, Crystal Glacier's, Robotica Farms's, Mystic Marsh's, and maybe Breeze Harbor's but for this one I got a glitchyish result so maybe it doesn't count (Zephyr's might be possible). I think it would be cool to add this category on speedrun.com and I have the video for each portal if anyone wants (done without Roll in Air glitch)
