It doesn't refer to a single, specific product but rather to a category of extra-large toys.

These "Super Big" or "Giant" surprise eggs typically include:

Size: They are significantly larger than standard candy or plastic surprise eggs (like a Kinder Surprise). They can range from the size of a melon to much bigger.

Contents: They contain multiple smaller surprise items, which can include:

Collectible figures or toys (e.g., action figures, dolls, squishies).

Blind bags or smaller surprise capsules.

Slime, putty, or other sensory compounds.

Stickers, trading cards, and other novelties.

Sometimes, cany or small chocolate items.
