Mountain Puffer is a Rare fish that can be obtained using the item Swollen Murloc Egg.

Swollen Murloc Egg will spawn a Murloc NPC, Swamprock Tadpole, that grants the buff Blessing of the Murlocs, increasing your chance to fish up Mountain Puffer.

There are a number of Rare fish in Legion, and items (bait or otherwise) that will help you catch them.
The Rare fish and items to catch them are zone specific (although some are obtainable on any shoreline of the Broken Isles).

Rare Fish

There are 18 rare fish coming in Legion that can be fished up. Each rare fish grants +5 to Fishing skill when used, consuming it in the process.

There are 3 Rare fish per zone, and 3 that can be caught on any coastal waters.
These can be fished up from a Fishing skill of 1, so this can be an effective way to power level Fishing.
Catching one of the rare fish listed below while fishing will grant the achievement A Cast Above the Rest. Catching them all will grant the achievement Bigger Fish to Fry, which is a requirement to get the Underlight Angler Fishing Artifact Weapon.
All Rare fish are Bind on Pickup.
If you are fishing with the Underlight Angler equipped, you will obtain a DIFFERENT version of each rare fish that grants Artifact Power instead of Fishing skill (e.g. you would fish up Coldriver Carp instead of Coldriver Carp)

Note that this does not retroactively apply to rare fish you obtained before getting the Artifact - the only use for these short of maxing fishing skill is vendoring for a decent chunk of change.

The Rare fish in the chart below are marked with a star (*)

Fishing Bait and Items

Some of the items that help you catch Rare fish will spawn and NPC that grants a fishing buff; others contain bait, or spawn NPCs that drop bait.

All fishing bait buffs last for 2 minutes once used (except for Rusty Queenfish Brooch and Ancient Vrykul Ring, which last 5 minutes each).
All buffs last the full duration, except for Moosehorn Hook, which expires as soon as you catch a bait.
Almost all baits can be bought/sold on the Auction House. Use this if you are having trouble with a particular fish!

The exception to this is the Stunned, Angry Shark, which has a 1 minute duration in your inventory.

All baits are Unique, meaning you can only carry one. The further caveat to this is that you WILL NOT catch any bait that is currently in your inventory!

This can be used to your advantage if you are looking for a particular bait in a zone - by having certain baits in your bags, you will ensure you do not catch them again.
If you are wanting to obtain multiples of the same bait, you can put baits on the Auction House, mail them to an alt, or put them into a Guild Bank or Guild Bank Tab that only you have access to. This will allow you to catch the same bait again.

A portable mailbox like MOLL-E (Engineering) or GUMM-E (from the Draenor garrison Engineering Workshop) is a huge boon when doing this out in the field!

It is worthwhile saving some rare fish bait, in order to level Artifact Power on your Underlight Angler if and when you get it.

Notes:
* Indicates a Rare fish
(1) Funky Sea Snail is an item that will summon a Bitestone Fishbrul that drops a Salmon Lure when killed.
(2) Swollen Murloc Egg is an item that will spawn a Murloc NPC, Swamprock Tadpole, that grants the buff Blessing of the Murlocs, increasing your chance to fish up Mountain Puffer.
(3) Rotten Fishbone is an item that will attract a Druid NPC (Lorlathil Druid) that casts the The Cat's Meow buff on you, increasing your chance to fish up Ancient Mossgill.
(4) Drowned Thistleleaf is an item that will grant the buff Blessing of the Thistleleaf, increasing your chance to fish up Thorned Flounder.
(5) Skrog Toenail is an item that will summon a Salteye Skrog-Hunter that drops a Aromatic Murloc Slime when killed.
(6) Rusty Queenfish Brooch is an item that is required to see Ghostly Queenfish pools in Azsuna.
(7) Using Sleeping Murloc will awaken a Confused Seerspine Murloc, who will run around briefly and drop some Seerspine Puffer into the water.
(8) Moosehorn Hook is an item that increases your chances to catch rare bait in Stormheim, rather than fish.
(9) Ancient Vrykul Ring is an item that is required to see Oodelfjisk pools in Stormheim.
(10) Message in a Beer Bottle contains Axefish Lure when opened.
(11) Using Stunned, Angry Shark will spawn a Landlocked Shark, which will yield Seabottom Squid when killed. Using it on land makes it much less dangerous than in water (hits quite hard).
(12) Decayed Whale Blubber is an item that attracts flies - Ravenous Fly can be looted from these.

This rare fish can be caught while under the effects of Swollen Murloc Egg which is obtained by fishing in highmountain.

Comment by 480715

Can you catch these rare fish in open water, or only in schools?

Comment by Alfa

Can confirm, you can fish these up in open waters.

Caught two during my two minute buff (back to back nonetheless).

Comment by tedh1

Caught this one with the buff from Swollen Murloc Egg. Both the Mountain Puffer and Swollen Murloc Egg were caught at:
/way thunder totem 53,84 68,51

Comment by SargonStarblade

Just in case anyone was wondering.

If you save up all the rare fish you collected while trying to get your Underlight Angler, like me, don't it won't work. The text is not changed once you get the Underlight Angler.

It still says:

Use: Toss the fish back into the water, increasing Fishing skill by 5, up to a max of 800.

Only new rare fish will say:

Use: Toss the fish back into the water, granting 50 Artifact Power to your fishing artifact.

Comment by MRTF

I used the Swollen Murloc Egg, but the buff was never displayed to me. Regardless I got the Mountain Puffer shortly afterwards so no need to panic even if the Blessing of the Murlocs isn't displayed.

Comment by RiokaR

After returning to the game and trying this, I was frustrated to realise I already had some of the lures in my bank, and as they are unique, I ended up wasting too much time fishing for nothing. This macro will check if you have an item hidden away in your bags or bank.

/run local id = "133711" local countBags = GetItemCount(id) local countTotal = GetItemCount(id, true) print(GetItemInfo(id)..":", countBags, "(bags)", (countTotal - countBags), "(bank)")

Swollen Murloc Egg: 0 (bags) 1 (bank)

You simply need to change the id to the correct item id you are searching for.

There are three Hightmountain Salmon Schools in Whitewater Wash at 42, 59.

Comment by Martika

For whatever reason, these have been fished up by people using the Salmon Lure item for at least 3 years (according to comment history.) Happened for me today, fished up about 20 with the Salmon Lure rather than the Swollen Murloc Egg.
