The Cuddly Conduit is the reward you're chasing: a rainbow town portal with butterflies and a look that recalls Whimsyshire. For players collecting D4 items, the important detail is what unlocks it. According to this Season 15 walkthrough, you need The Perfect Cupcake from Neigh'relle, the boss inside Whimsyshire. The cosmetic arrives with Patch 3.2.3 during the Season of Hell's Legacy, and there's no shop purchase involved. Your time goes into reaching the encounter and getting another chance at the drop.

Watch for the purple beam

The Perfect Cupcake is described as a Mythic reward, so look for a purple beam after Neigh'relle falls. Picking it up adds Cuddly Conduit to the Town Portals section of your Wardrobe rather than leaving an item in your regular inventory. Don't expect a fixed number of attempts. The supplied account mentions player reports ranging from twenty to one hundred victories, but that isn't a guaranteed window. A dry stretch doesn't mean you've missed a required step, and another player's quick drop doesn't predict yours.

Keep repeat visits short

Once you've reached the boss, finding another entrance can become the slow part. The walkthrough describes a party finder reset that starts after the encounter. Join a group on a different Torment tier, decline the invitation to teleport to its leader, then leave. Its example uses Torment 10 and Torment 12 as the two difficulties. The claimed result is a return to your original tier inside a fresh Whimsyshire instance. Treat that behavior as something to check, not a promised feature that will always work.

Defeat Neigh'relle and inspect the drops.
Join a party on another Torment tier.
Decline the teleport prompt, then leave.
Check whether Whimsyshire has reset.

Choose your entrance before setting out

For initial access, Liquid Rainbow is the most direct option described here. It's listed as the Rank 5 Season Journey reward and opens the entrance when used outdoors. Already spent yours Treasure Goblins offer another possibility. Hunt them in active Helltides or try Echoing Hatred for a concentrated group. The Waking Nightmare dungeon Diablo Hellfire The Cornerstone is another suggested route, although portals appearing after elite kills may send you somewhere else. That uncertainty matters when you've only got a short session.

Route Main consideration
Liquid Rainbow Requires the journey reward
Treasure Goblins Entrance depends on chance
Waking Nightmare Destination may vary

Spend your effort on boss attempts

Keep the goal separate from ordinary progression. Comparing equipment or budgeting D4 Gold won't replace the encounter required by this route. Once inside, learn the path to Neigh'relle and check each reward pile before moving on. If the reset doesn't behave as described, return to the entrance options rather than repeating an unsuccessful sequence. The useful measure is completed boss attempts, not how long you've spent searching for another rainbow portal.
