You can merge overlapping shapes in Adobe Illustrator by using the Unite option in the Pathfinder panel.

Merging Overlapping Shapes: A Step-by-Step Guide

Here's a detailed explanation on how to merge overlapping shapes:

Select the Shapes: Using the Selection Tool (V), click and drag to select all the overlapping shapes you want to merge. Ensure all shapes are fully selected to achieve the desired outcome.
Access the Pathfinder Panel: If it's not already visible, go to Window > Pathfinder to open the Pathfinder panel.
Unite the Shapes: In the Pathfinder panel, click on the Unite button, which is located on the left of the top row. This will combine all selected shapes into a single compound path.

Let's say you have several overlapping circles that you want to combine into a single blob-like shape.

Step 1: Using the Selection Tool (V), select all of the overlapping circles.
Step 2: Go to Window > Pathfinder.
Step 3: In the Pathfinder Panel, click Unite.

After clicking unite, all the overlapping circles will merge into a single shape.

The Unite function is a non-destructive operation, meaning you can revert to the original shapes by undoing the step immediately after it.
Keep in mind the original color of the shapes might change. If the shapes had different colors, the resulting merged shape typically takes on the color of the top-most shape.
