The "Minions Surprise Egg for Boys" is a common type of novelty candy product, and its exact contents and packaging depend heavily on the brand and the country it's sold in.

However, the generalconcept of a Minions Surprise Egg is:

1. The Outer Shell (The Treat)

The egg is typically made of a confectionery treat, which is usually:

Chocolate: A hollow chocolate shell (like a traditional Kinder Surprise).

Kinder Joy Style: A plastic egg that separates into two halves: one side with a creamy treat (milk and cocoa creams with wafer balls), and the other side with the surprise toy.
