or at least, these are the toys taking up slots on the side bar/ most frequently used.
Yes! I use it for this WQ all the time. It’s probably my most used toy. 
Stylish Black Parasol
I have the rainbow generator, the black parasol that reduces fall speed (works like levitate) and the eternal hearthstone. Most other toys are useless.
the new toys that changes the weather and zone style lol
We just need an Auctioneer toy now and were good
just use your Long boi mount. 
I wasn’t smart enough to buy one 
hopefully we see a recolor with the same function on the Trading Post
Others I’m forgetting but those are the main ones.
It WAS the D.I.S.C.O. ball, but since it was given out via Twitch a while ago, I don’t use it much anymore.
It’s a toy you can “share” and I enjoyed how rare it was. Still semi-rare.
You put down a goblin disco ball everyone else can click on, and it plays goblin music and makes you dance.
These days, I find myself using Shuffling Sands, which makes you dance really fast and walk really slow, for 10 minutes. It’s just funnier to play with.
Rainbow Generator gets an honorable mention, because you can make an impromptu pride parade at any moment, pretty hilarious in PvP as well.
puntable marmot
There’s another one from DF? Does it share the cooldown with Katy?
Alas, yes it does. It’s from the centaur faction renown.
It’s faster(*) than a ground mount on water and you can fish from it.
In the pathfinder days, it was very useful for traveling along coastlines until flying came out. In Dragonflight, I’ve used it now and then in the tuskarr fishing areas with a lot of pools scattered across open water.
In this genre, though I don’t have it, I’d like to mention the Condensed Water thing. Basically spawns a ball of water that you can fish. I generally loathe fishing, but, that and the Anglers Raft are both on my “someday” lists.
That cursed tome that gives you a permanent blue “cursed” look. I use it at all times on my Death Knight, I’d hardly recognize him without it.
Seafarer’s Whistle is the toy with the most unique opportunities to put to good use.
Ah, shame, no reason to rush out and get it, though it’s probably easier to get than Katy now.
Sadly it’s not a toy - I wish they would make it one - but my Arcanite Ripper I got back in TBC is my favorite flavor item in game. I like it so much I was maining a paladin in SL… my Ripper was on another paladin so I faction changed, server transferred, leveled up, and re-geared the same class just so I could have it.
(I was kicking myself for not just doing that in the first place but I didn’t really want to pay for it at the time)
