Find the Brainrot Morphs: How to Get Puffino Builder and Gattino Hydra

The latest batch of additions to Find the Brainrot Morphs brings the roster to 173, and two of those entries are new: Puffino Builder and Gattino Hydra. Neither one requires a puzzle, a key, or a timed event. One is sitting in the open on a rooftop, and the other is buried under the map behind a single TNT blast.

Quick answer: Touch Puffino Builder on the wooden platform on top of the Empty Base roof, then carry the red TNT block from the rainbow slide to the dirt patch marked with white X’s, detonate it, and drop into the hole to touch Gattino Hydra.

Puffino Builder and Gattino Hydra rarity and location

The two morphs sit at opposite ends of the rarity scale, which also matches how hidden they are. Puffino Builder is a Common and is visible from the air. Gattino Hydra is a Secret and cannot be seen at all until the ground is blown open.

Puffino Builder	Common	Wooden platform on the Empty Base roof
Gattino Hydra	Secret	Underground room opened by TNT on the marked dirt patch

How to get Puffino Builder on the Empty Base roof

Head to the building labeled Empty Base. You are aiming for the roof, not the interior, so line yourself up outside it before going vertical.

Get up top. A flight item makes this trivial, but the climbable structures around the base work too if you do not have one equipped.

Walk into Puffino Builder where it stands on the wooden platform on the roof. Contact is all that is needed — there is no prompt to hold and no item to bring.

How to get Gattino Hydra with the TNT blast

Gattino Hydra is the Secret of this pair, and it only exists in a sealed pocket beneath the map. The entrance is created by one explosion on one specific tile, so the whole task is really about getting the TNT to the right square of ground.

Pick up the red TNT block near the rainbow slide structure. Your character carries it, so avoid long detours that risk a reset.

Take it to the brown dirt area painted with white X’s and a TNT symbol. That marking is the only valid detonation point for this morph.

Set off the TNT and let the blast clear. The dirt breaks open into a shaft leading down.

Drop into the hole and touch Gattino Hydra in the room below. The counter ticks up the moment you make contact.

Touching a morph adds it instantly and pushes the Collected counter up by one.

Note: If the ground does not break, the TNT was almost certainly dropped somewhere other than the marked patch. Re-grab a block from the rainbow slide and check that the white X’s are directly under it before triggering the blast.

How to confirm both morphs were collected

The Collected counter is the only confirmation you need. Each successful pickup raises it by one out of 173, so a player sitting at 166 finishes this pair at 168. There is no separate claim screen and no delay.

The Morphs menu open, listing collected and missing entries in the collection — The Morphs menu lists everything collected so far and shows which entries are still missing.

To double-check an individual entry, open the Morphs menu from the side buttons. Both Puffino Builder and Gattino Hydra appear there by name once claimed, and you can equip either one straight from the list to see its animation and sound.

Morphs collection screen open while a red character morph is equipped on the player — Browsing the collection with a morph already equipped, which is how you verify a new entry landed.

Both pickups take a couple of minutes together if you already have a flight item. The only real failure point is the TNT step, and it is a positional problem rather than a timing one — put the block on the marked dirt, and the route down to Gattino Hydra opens every time.
