I think a bat flew in my house and bit Garrett

Calm down! NOT FOR REAL! He is suddenly obsessed with Batman, hence the title. He's actually obsessed with all superheros.

Jimmy bought this Lego set on vacation and Garrett bothered him daily until Jimmy opened the box and put the set together.

Here's Jimmy. You can see all of the Lego pieces on the table. The pieces are now sorted into the correct piles to assemble.

Garrett checks out the back of the box. He tells us that he wants ALL the other sets to finish his "collection." Once Garrett buys a toy that has other toys advertised on the back of the box he wants ALL of them!
Dad reads the instruction booklet and Garrett supervises.
My boys with the assembled Legos.

A closeup of the assembles Legos. The kit contained Robin and his car and The Penguin, his vehicle, and two tiny penguins. Garrett insists on calling Penguin Mr. Penguin, or Mr. Penguin Man.
