Merge Animals 3D is a casual game where you take a human and merge them with different animal parts to create a strange being and play through different settings with very different surfaces. This means that you'll need to merge body parts from sea, land and flying creatures to beat your opponents.
In the lab in Merge Animals 3D, you'll find a human body that is waiting to be merged. At the bottom of the screen are different serums you can unlock and inject as you gradually unlock the different jars. Each serum contains a different animal's genetic information for modifying the character's body.
When you finish merging, all you have to do is tap the green button on the right of the screen. Doing so will start a fierce fight to reach the finish line in first place. Over land, sea or air, you will need to test your character's ability to beat the rest of the competitors in these combined tests.
Merge Animals 3D has an entertaining gameplay for testing this human's mutations. By choosing different animal parts, you can move around each race track and try and cross the finish line first. If you manage to do this, you will receive rewards that let you get new jars for different species.
