Grey Mouse Pet in Grow A Garden: Value, Buy, and How to Get It

What is the Grey Mouse pet?

The Grey Mouse is a Legendary pet added during the Blood Moon Event Update. Most players recognize it as a movement-focused utility pet rather than a farming or duplication pet.

Key basics:

• Rarity: Legendary
• Hunger: 15,000
• Main role: Movement speed + self experience gain
• Game platform: roblox

Appearance

The Grey Mouse has a blocky, stylized look that fits the Grow A Garden pet design style. Its body is light gray with a square head and compact legs. The ears are large and box-shaped, with a soft pink inner section that stands out clearly against the gray body.

It has simple black eyes and thin black whiskers extending from each side of its face, which makes it easy to identify even at a distance. Overall, the design looks clean and neutral, without extra effects or glowing parts, which is typical for utility-focused pets.

How do you get the Grey Mouse pet?

Obtaining method: Mythical Egg

In general, most players get the Grey Mouse by hatching Mythical Eggs during the event period or from saved eggs afterward.

Mythical Egg Pet Chances

Because the Grey Mouse has one of the highest drop rates in the Mythical Egg, most players obtain it relatively early compared to other Legendary pets.

Buying the Grey Mouse directly

Some players choose not to rely on egg hatching and instead buy the Grey Mouse pet directly from U4GM.

• Listed price: $2.99

This option is usually chosen by players who want guaranteed access without spending time or resources on eggs.

What does the Grey Mouse actually do?

Passive abilities

Whisker Wisdom

• Gains about 500 bonus experience every 10 minutes
• The bonus XP only applies to the Grey Mouse itself

Movement Speed Boost

• Increases player movement speed by about 10%
• The speed bonus usually increases slightly as the pet gets older

In practice, most players use the Grey Mouse mainly for faster movement around their garden and nearby plots. The experience gain helps the pet level steadily without active management, but it does not help other pets.

What is the value and rarity of the Grey Mouse?

• Tier: Legendary
• Direct purchase price (U4GM): $0.98
• Drop rate from Mythical Egg: High compared to other Legendary pets

Value analysis

Based on its Legendary tier, relatively high drop chance, and low direct-buy price, the Grey Mouse is generally considered a low-to-mid value Legendary.

Most players see its value as:

• Useful early or mid-game
• Not rare enough to be considered a prestige pet
• Practical rather than powerful

Its value mainly comes from convenience and speed, not from farming efficiency or resource duplication.

Should you buy the Grey Mouse?

For most players:

• If you already open Mythical Eggs, it is usually better to wait and hatch one naturally.
• If you want movement speed immediately and do not want to rely on chance, buying it can save time.

In general, players focused on optimization often skip buying it and use eggs instead.

Is the Grey Mouse worth using?

The Grey Mouse is worth using if:

• You want faster movement around your plot
• You prefer passive, low-maintenance pets
• You are early in progression and lack speed bonuses

It is usually not worth using if:

• You already have pets that boost farming or duplication
• You are late-game and prioritizing resource efficiency

Most players eventually replace it with more specialized pets, but many still use it temporarily for comfort and mobility.
