A Bug’s Land was the first “big” addition to Disney’s California Adventure after it opened. Although Bountiful Valley Farm and Its Tough to be a Bug opened with the park in February 2001, the land opened over a year after the park opened.
Opening in October 2002 in response from guests that it lacked “kid friendly” attractions. Originally to be called Flik’s Fun Fair with a few attractions, the land “expanded” to include the Bountiful Valley Farm, and changed name to a bug’s land. The area is themed as though guests are actually bug sized. Oversized human items and foodstuffs are scattered around the land, similar to the Honey, I Shrunk the Kids play area at Disney Hollywood Studios.
You might ask how do bugs and DCA’s California theme connect, well as with everything in Disney the Imagineers created a story behind it.
It reveals that Flik and the other bugs were inspired to create their own fun fair when Disney's California Adventure opened next door to them. When the Imagineers set out to build the Twilight Zone Tower of Terror, they discovered the bugs in the garden and decided to open up Flik's fair to park guests.
