Speed is the stat that decides everything in Steal an Egg. It controls which biomes you can walk into, how far you get before a guardian flings you across the map, and whether the egg you just grabbed actually makes it home. Every other upgrade in the game exists to feed it.
Quick answer: Stand on the Treadmill to gain Speed over time, spend pet income on Treadmill upgrades to raise the gain per second, and equip the highest-tier Trail you can afford — the Trail multiplier applies to everything the Treadmill gives you.
Speed requirements for every biome
There are nine biomes, and each one has a minimum Speed before its guardian stops treating you as harmless. Walk in under the threshold and the guardian can catch you, ragdoll you, and knock loose whatever egg you were carrying. These numbers are your training targets.
| Biome | Speed needed |
|---|---|
| Forest | None |
| Lake | 900 |
| Desert | 10K |
| Jungle | 40K |
| Snow | 170K |
| Volcano | 700K |
| Abyss Ocean | 2.5 million |
| Prehistoric | 17 million |
| Cosmic | 700 million |
How Treadmill training generates Speed
The Treadmill sits at your base and is the primary Speed source in the game. You jump on it, and Speed accumulates for as long as you stay on it. There is no trick to it — time on the machine is the resource.
That money comes from pets. Hatched pets sit in your pen and generate income passively, and that income is what pays for Treadmill levels. Note that upgrading your base itself does not raise Speed — it raises how many pets you can store, which raises income, which then pays for Speed.
Trail multipliers, from Grey to Divine
Trails look cosmetic, and they do leave an animated effect behind you, but the real function is a multiplier on the Speed you gain per second while training. There are 10 of them, running from Common up to Divine rarity, and they are bought from a dedicated Shop.
Because the multiplier applies to Treadmill gains rather than to a one-time payout, a Trail upgrade is worth more the earlier you buy it. Do not buy every tier on the way up — save and jump to the strongest one you can reach.
| Trail | Speed multiplier |
|---|---|
| Grey Trail | x1.5 |
| Green | x2 |
| Blue | x2.5 |
| Purple | x3 |
| Golden | x3.5 |
| Red | x4 |
| Galaxy | x5 |
| Secret | x7 |
| Eternal | x10 |
| Divine | x14 |
Index rewards give free Speed for new pets
The Index tracks every pet you have discovered, and each new entry unlocks a reward containing Speed and Cash. Rarer pets pay out more of both. It costs nothing beyond the eggs you were already stealing, so open the Index after every hatch and claim anything sitting there.
Filling the Index out completely also hands you a better melee weapon, which is used to knock other players around when they are carrying something you want.
Speed Shop boosts bought with Robux
The Speed Shop sells Speed outright for Robux, in packages ranging from +150K up to +1B. That top tier is the only realistic shortcut to somewhere like Cosmic, which asks for 700 million Speed on its own.
None of it is required. Every biome is reachable through Treadmill training, Trail multipliers and Index rewards; the shop only removes grinding time.
What to upgrade first
Speed upgrades take priority over base upgrades in most situations. A bigger base holds more pets and earns more money, but higher Speed reaches the biomes where the high-earning pets live in the first place. Get the Speed, then the pets pay for the next round of Speed.
| Situation | What to buy |
|---|---|
| Short of the next biome’s threshold | Treadmill upgrade, then keep training |
| Training feels like it has stalled | Next Trail tier you can afford |
| Escapes are consistent, income is not | Base upgrade for more pet slots |
| Just hatched something new | Claim the Index reward |
Why you still get caught above the listed Speed
Meeting a biome’s number does not guarantee a clean run, because eggs have weight. Large eggs slow your character the moment you pick them up, and on the heaviest ones that slowdown can eat your entire Speed advantage. Training roughly 15 to 20 percent past the listed requirement covers it.
Where the guardian catches you tells you what to fix. Caught close to your base means you are a Trail tier away from making it. Caught around the halfway point means you are genuinely under-trained for that biome and should head back to the Treadmill. If your character visibly bogs down the instant you lift an egg, that egg is too heavy for your current Speed — take a smaller one from the same biome.
Tip: egg spawns reset every five minutes, with the map closing for 13 seconds between cycles. Use that window to train rather than standing around waiting.
The loop never really changes. Steal what you can carry, hatch it, let the pets pay for a better Treadmill, buy a stronger Trail when training slows down, and push one biome further. You can check the current version and jump straight in on the Steal An Egg Roblox page.
