Three kinds of fights run on 30-minute timers in every server. Each one pays its own currency, which buys boosts, mutations and limited eggs, and each win also counts toward a milestone track with free pets.
Dr. Scramble takes over the map in his Mecha. Beat him with the other players in the server.
Rewards: Samples, 1 Boss Mastery point per win, and a very rare chance at the Divine Mecha Scrambler.
Scrap, Reactor and Augmented drones spread over the map. Tougher drones drop more.
Rewards: Samples and, sometimes, a Drone Part for the Stolen Experiment Vault.
A Rift opens somewhere on the map. Step inside and fight the Overlord. When it faints, hit its hand with your bat: every hit does 100 damage.
Rewards: Boss Tokens for the Boss Shop and Boss Mastery points (rewards include eggs that already have the Fractured mutation).
Each server keeps its own boss clock. Press the button when a fight starts in your server and the timer counts down to the next one. It is saved in this browser.
Every win against Dr. Scramble gives 1 Boss Mastery point. You can fight at most about twice an hour, so the planner assumes 2 wins per hour of play.

How often does Dr. Scramble spawn in Steal An Egg?
About every 30 minutes in each server. Every server runs its own clock, so start the timer above when you see him arrive and it will count down to the next one.
How do you get Boss Tokens in Steal An Egg?
Beat the Rift Overlord. A Rift opens about every 30 minutes; go in, and when the Overlord faints hit its hand with your bat (100 damage per hit). Spend the tokens in the Boss Shop.
How do you get Samples in Steal An Egg?
Beat Dr. Scramble's Mecha or his drones. Spend Samples in the Experiment Shop on the Scrambled mutation, boosters and limited eggs.
What do you get at 100 Boss Mastery?
The Pink Dragon Experiment #010 (Eternal, 2.5B/s). You get 1 point per win, so it takes 100 wins, about 50 hours of play if you catch every fight.
How do you get the Mecha Scrambler?
It is a very rare drop from beating Dr. Scramble's Mecha, a Divine pet that earns 7.5B/s. There is no pity for it, so it is pure luck.
