Icon AThe Omniblob, five-eyed slime boss.
Icon BKraken Rex on a sea-green sky.
Icon CThe Eternal Lantern, purple and pink.
Icon DAn open Master Class chest with its monster.
One badge for completing each family (Roblox crops badges to a circle).
Basic to Master Class. Each family is a collection of 9, like CS2 cases: rarer chests give fewer low monsters. Odds are shown before every craft or purchase.
A trait (Cash Burst, Coin Magnet, Hype Beast, Lucky Aura, Time Warp, Shiny Sense, Guardian), a lore line, a signature dance, and a rare Shiny version (x3 income).
Shared window, value estimate, fairness warning, both accept, 5 second countdown. Any change resets it. The swap can never duplicate monsters.
Hold E on a monster in an unlocked plot and carry it home. Lock your plot on the red pad. Weapons only hit thieves and intruders.
Sell monsters, or gamble one (99% a Monster Part, 1% Ascended x100). Rebirth for more cash, luck, faster chests and new weapons.
Press F on any monster: hearts, a happy dance and +25% income for a minute.
Day and night, fireflies, shooting stars, floating islands, waterfalls, wild monsters roaming, and events: Starfall, Golden Hour, Blood Moon.
A 7-day login streak and playtime gifts at 3, 8, 15, 25, 40 and 60 minutes.
The UI scales for every screen and stays clear of the thumbstick. The first minute is a guided tutorial.
Taken in the game itself (Roblox Studio playtest).
Monsters on display with traits and income, the chest line behind them.
Icon buttons, cash pill with rebirth bar, live boost chips.
Tabs, value tags, real cash amounts, gifting.
Shared window with values and a fairness warning.
3x3 grid (drag) and one-click Buy + Craft.
Daily streak and playtime gifts.
World events change the sky and the rules.
HUD scaled for phones, clear of the thumbstick.
All of these exist on the Roblox experience now. Ideas come from the top charts (Steal a Brainrot, Grow a Garden, Pet Simulator 99, Adopt Me).

Every model was made for this game. Each monster has its own signature feature, and higher rarities get orbiting crystals, wings, crowns and glow.
The 3D models belong to the zKikobr account: on another account they show once that account is a collaborator or has access to the assets.
