As the owner suggests, the snake likes to eat birds. Fortunately, you can pick up a robot bird from Giuseppe's Toys and feed him that instead. But first you have to catch up to him.
He goes:
1) outside the store
2) across the atrium to the east wing of the mall
3) inside MacGuffin's (in the small portable potty)
4) inside Sizzle (in a tanning bed)
5) to the Chinese Food stand in the atrium
Feed him a robot bird from the toy store, but he shows up again to steal your scooter after you chase the crook driving the security cart.
At first he is in his glass tank at Crawl Mart. But he gets out and leads you on a merry chase. You might tempt him with a snack: get a robot bird from Giuseppe's Toys. Follow him into the right wing, to MacGuffin's then to Sizzle, then to the Chinese food stand in the atrium food court. Feed him the bird and he slithers away.
The favorite snack of Eddie the snake (as mentioned by his owner) is birds. But you can get a robot bird from Giuseppe's Toys. You still have to catch up to the snake to feed it to him.
No one knows, and you do not have to find him. Eddie will come back to help out in the end.
You get a robot bird from Giuseppe's Toys. After you chase Eddie to MacGuffin's, then Sizzle, then the Chinese Food stand, you feed him the snake. But he just slithers off.
Follow the snake into the east end of the mall, to MacGuffin's, then to Sizzle, and finally back to the atrium at the Chinese food stand. Use the robot bird, but he swallows it and runs off.

You first run into the masked robber (complete with moneybag?) when you have fed Eddie the snake and go to check on a security outage at Carnival Costumes. You surprise him at MacGuffin's and get the key to the back room at Good Deals.
No
There is not a literal snake, but one of the concentration camp leaders is nicknamed "the snake".
You are checking on Eddie the snake. He has gotten out of his tank and into the mall. Chase him left across the atrium to the other wing of the mall. He will be at MacGuffin's, then at Sizzle, then back in the food court at the Chinese Food stand.
You have to chase the crook through the vents and escalator machinery, cutting through the blocking grates with the blowtorch. When you catch him, you both plummet into the atrium fountain, where he is kayoed by Eddie the snake. For the full solution, see the related question below.
You only have the scooter when you are chasing the security cart around the mall. You use the password (frost) to get it from the Manager's Office, and charge it with the charger device from MacGuffin's. After you chase down the cart, Eddie the snake has the scooter (and may still have it when you leave).
