The children's astounding psionic and extrasensory abilities and Emma's attachment to Mimzy alert their parents, especially their mother, and Larry White, Noah's science schoolteacher, to the devices. Later, Noah accidentally fuses the card with a blue blob, causing it to turn into a "generator" that causes a power black-out over half the state of Washington, alerting the FBI to their activities. The family is held for questioning by Special Agent Nathaniel Broadman (Michael Clarke Duncan), and it is revealed that Mimzy is actually a highly advanced form of artificial life utilizing nanotechnology created by Intel. After this, Emma tells everyone the message Mimzy is relaying to her from humanity's distant future. She explains that pollution will eventually corrupt humanity's DNA, and that many rabbits like Mimzy have been sent to the past, since no natural life forms can survive time travel, but none of them successfully returned. Mimzy is the last one remaining, but is now beginning to disintegrate. The reason for the deaths of all the other rabbits is the "chosen ones" before Emma had no "engineers" (like Noah) to help build the bridge across time. Emma and Noah must build the bridge by using the other toys to activate a time portal, so that they can return Mimzy to the future with uncorrupted 21st-century human DNA that the people of the future can use to correct the damage to their DNA caused by ecological problems.
