Masiosaurus

It is a free Roblox simulator by xFrozen x Dudes. You split the sea with a staff, carry an egg back before the waves close, hatch an animal, and earn Cash from animals at your base.

Stand in the Safe Zone, hold the left mouse button to charge the staff, and release when the bar is full. A stronger staff and higher Power keep the opening up longer.

A wave or guardian hit drops the egg and throws you back to the Safe Zone. Shorten the route or raise Speed, then retry that same egg.

Current code lists say Release gives a Bat, often described as a rare Bat. Enter it once in the Shop code box and check the animal roster. It can already be used or expired on your account.

Yes. The official description says animals earn Cash offline, and Roblox Plus players get 15% extra Cash. No offline time cap is published.

The September 29, 2026 guide says no. Rebirth spends Cash, starting at 25,000 for a 2x multiplier, and leaves animals, upgrades, and store purchases. Read the confirmation panel in case a Saturday update changed that.
