Kablooie was a blue chewing gum that was sold on Earth between 2047 and 2051.
Mobius M. Mobius and a group of TVA hunters traveled to 1549 to the Aix-en-Provence to investigate one of the attacks against the TVA. Having encountered a boy who witnessed the attack, Mobius asked him about his teeth, which were tinted blue. He then handed Mobius a pack of Kablooie.
Kablooie gum was a piece of evidence proving that a nexus event had occurred in 1549, with Mobius instructing Hunter U-92 to run the gum through their system for any information. While they found nothing, a conversation with Loki led Mobius to return to the gum, and began to search its history in search of a rogue Loki variant. They discover that Kablooie was sold between 2047 and 2051; using this information, they sifted through various natural disasters that occurred in those four years before arriving at 2050 Alabama, where Roxxcart was located.
