unicorns if I remember rightly.

I posted this on the second page of the Maze thread in the Events Forum.

It came from Discord.

HellOw, it's Ask-Bot, your favorite mission guide! ,


Today, I’d like to go over some of the obstacles in Power City and the types of horses that will help you overcome them! Let’s start with holes!
I recommend a [b]“Pegasus” type[/b] horse to get through them. If you don’t have one, you can find Pegasus Blood on the Black Market pretty easily.

Now take a look at these narrow passages between boxes… Only small horses, like [b]ponies, foals, or even Falabellas,[/b] can squeeze through!

As for rainbow roads, it’s both easy and magical: you’ll need to ride a[b] Unicorn[/b]! Finally, heavy obstacles like large boulders or massive crates won’t stand a chance against your[b] draft horses,[/b] whether they’re divine or not!

also this info is found in the dedicated mazes topic in the events forum
