Should I keep Mouse after hatching Bunny?

Usually no. Bunny’s Hop boost is also growth-oriented at a higher editorial tier (C). Mouse becomes collection filler unless you specifically need a second common for a temporary slot.

Is Mouse the same pet as Mochi Mouse?

No. Mouse is a common with Nibble. Mochi Mouse is a legendary with Sweet Roll for honeyed mutation and event currency. Confirm the slug in trades.

Mouse is the common you hatch when the egg gives you almost nothing else — Nibble’s tiny growth speed boost is honest about how small the effect is.

Mouse weight progression

Mouse hatches at 0.4 kg and grows with the formula W = (hatch ÷ 11) × (age + 10). The table below projects its weight at each age milestone so you can plan trade timing and weight targets.

Mouse weight by age
Age	Projected weight
Age 1	0.40 kg
Age 25	1.27 kg
Age 50	2.18 kg
Age 75	3.09 kg
Age 100	4.00 kg
Age 125	4.91 kg

Playstyle

Use Mouse on fast, low-stakes rows while you wait for a better growth pet. Editorial tier D common places it near the bottom of the usefulness index; common rarity only means it appears in early eggs. Swap to Bunny Hop boost or Cat Nap as soon as those species show up. Nibble does not claim mutation help, pest defense, or sell bonuses — keep expectations microscopic.

Weight & trading

Hatch 0.4 kg stays tiny on the curve: age 50 ≈ 2.2 kg and age 100 = 4 kg via (0.4 ÷ 11) × (age + 10). Investing toys into Mouse for weight is usually poor opportunity cost next to aging a tier C common instead.

Nibble: tiny growth speed boost. No percent, no radius, and no stacking rules appear in pets.ts. Treat overlap with Bunny Hop boost as unresolved in data — if both are out, watch which effect the tooltip emphasizes rather than assuming multiplicative stacking. Mochi Mouse is a separate legendary with Sweet Roll; sharing the word “mouse” does not share abilities.

Fast cycles where tiny speed still registers

On crops that finish in very short loops, a small growth nudge can mean an extra harvest across a long session. On multi-hour trees, the same nudge is hard to notice next to Koala Eucalyptus or Cat Nap.

Avoid parking Mouse beside Sloth Slow Growth on the same goal: one species wants speed, the other extends timers. Pick a lane per plot.

Collection filler versus roster dead weight

Keeping one Mouse for collection percentage is fine. Aging it past early teens while better commons sit hungry for XP is usually a mistake given tier D ranking.

Trade value for common Mouse is typically negligible. Do not price it like Mochi Mouse or any legendary rodent lookalike — verify the slug before any exchange.
