The Honkai Star Rail Critter Pick event has become a quiet laboratory of chance and care. In the 2026 rotation, players are once again mixing cat-like lifeforms, waiting for the spark of a special mutation, and assembling a collection of Rare Creations that mirror familiar faces from the Astral Express and beyond. Think of the event as a living patchwork quilt: each square is cut from a base critter, stitched with a rare material, and ironed into shape by the heat of a mutation event. The loop is simple on the surface, but the catalog is surprisingly dense.

Event Basics and the Mutation Loop

Players begin with base critters and nurture them to record traits. The real goal is to trigger Special Mutations by mixing compatible critters and then feeding a specific item. Those items function like genetic tuning forks, awakening a dormant shape that turns an ordinary critter into one of nine Rare Creations. Once a Rare Creation is recorded, the game allows leftover critters to be sent out for adoption, clearing inventory space for the next round of experiments.

Rare Creation Recipes and Material Locations

Trash Cake

Trash Cake is often the first Rare Creation a Trailblazer unlocks. Its skin resembles a trash can with a dark filling, making it both easy to obtain and oddly endearing. The tutorial hands players this creation automatically, but it can also be forged manually by adding a Trash item during a Mutation Event. Trash is found by interacting with trash cans scattered across various worlds.

Rice Dumpling

Rice Dumpling requires a Leaf of Imaginary. After the creation is born, the Trailblazer messages Dan Heng and remarks that the critter reminds them of him. It may take several nurturing rounds with two critters to line up the correct traits for the Special Mutation. The Leaf of Imaginary drops from enemies in Backwater Pass in Belobog, Jarilo-VI, or can be bought from the Grocery Stand in Exalting Sanctum on the Xianzhou Luofu.

Ice Cake

Ice Cake is a frost-toned Rare Creation that closely resembles March 7th. The Trailblazer shares the news with March 7th by text. Its required item, Core of Ice, is available from the Administrative District Shop in Belobog or by defeating Everwinter Shadewalkers in the Fading Echoes.

Lambda's Friend

Lambda's Friend is gated behind the event's adventure mission. Players need to complete that mission before more Rare Creations can be unlocked. The required Seed can be earned through Assignments by selecting The Blossom in the Storm. Seeds also drop from destructible crates in Jarilo-VI or can be purchased in Central Starskiff Haven on the Xianzhou Luofu.

Sesame Cake

Sesame Cake is a Blade-shaped Rare Creation with a sharp, brooding look. When contacted, Silver Wolf replies on Blade's behalf, adding a layer of humor to the collection. Its mutation item, Vortex of Wind, can be farmed from Mara-Struck Soldiers in Cloudford, bought from a shop in Central Starskiff Haven, or obtained by breaking destructible objects in Jarilo-VI.

Troublemaker

Troublemaker resembles Guinaifen, and the character is thrilled by the idea of meeting her critter doppelgänger. The required Phlogiston appears by destroying destructible objects in Herta Space Station, is sold in the Administrative District Shop, and drops from enemies in Backwater Pass in Belobog.

Wisteria Cake

Wisteria Cake channels Herta's distinctive appearance. Herta's response is automated and uninterested, which fits the character. Virtual Particle, the key item, can be collected by breaking destructible objects in Herta Space Station or defeating enemies in the Storage Zone. It is also available from a shop in Central Starskiff Haven.

Lucky Snack

Lucky Snack resembles Qingque, who immediately wonders whether the critter can play Celestial Jade. Feather of Flame is the item required. It can be gained by breaking destructible objects in Jarilo-VI, purchased at a shop in the Administrative District, or farmed from Mara-Struck Soldiers in Cloudford on the Xianzhou Luofu.

Shader Cat

Shader Cat echoes Kafka's style. Silver Wolf intercepts the message and forwards the image to Kafka, turning the discovery into a relay moment. The Eye of Lightning is sold in the Grocery Stand in Exalting Sanctum on the Xianzhou Luofu and also drops from enemies in the Corridor of Fading Echoes in Jarilo-VI.

Completing all nine Rare Creations is less about grinding and more about targeted material hunting. The event rewards patience with a gallery of character-inspired critters and text interactions that reveal small character moments. As a culinary crucible, Critter Pick turns common drops like Trash and Seeds into collectible oddities, proving that even low-value materials can become the missing ingredient in a rare recipe.
