Inflatable alien costume (1075 Valencia Avenue)

Green and blue inflatable alien costume, with operating and inflating instructions.

According to Google Lens:

Niest inflatable costume, specifically the "Alien Kidnapping" style. The process requires a fan blower, a battery case, and 4 AA batteries (not included) to inflate the suit. These instructions are available in six different languages, including English, Spanish, French, German, Italian, and Japanese.

Battery & Blower Setup
Step 1: Open the bag.
Step 2: Open the battery case and put in 4 batteries.
Step 3: Take out the blower and twist off the top cover.

Installing the Blower
Step 4: Find the blower and place the opening. Step 5: Put the blower in the round hole of the costume.
Step 6: Use a ring to hold the blower in place.

Final Costume Setup
Step 7: Put the battery case in the built-in pocket.
Step 8: Place carefully to prevent accidents.
Step 9: Switch on the battery when you're done.

Built into it is a portable, battery-powered blower unit designed to inflate costumes or small inflatable structures.
The blower typically requires 4 AA batteries and is connected to a battery pack for operation.
Such blower units are common accessories for inflatable cosplay outfits, such as dinosaur or cartoon character costumes.

I cut off the green shoe covers at the end of the green pants due to wear, but the elasticized ankles are intact. The rest of the costume is in good condition.
