Loonis was born in the sewers beneath the town, mutated by the toxic waste that flows there and as such, has always been an outcast, shunned for his appearance and odd behaviour. His life changed when he met Eek, who saw beyond the paper bag and recognized a kindred spirit. Together, they formed an inseparable duo, with Loonis quickly adapting to Eek’s chaotic lifestyle. Despite his small size and nervous demeanour, Loonis has proven to be a valuable partner in their schemes, often coming up with the last-minute solutions that save them both.​

Loonis is the perfect sidekick to Eek, sharing his love for chaos but with a more cautious, anxious approach. Despite his jittery nature, Loonis has a mischievous streak of his own, often adding his own twisted ideas to Eek’s already wild antics. While Eek might be the instigator, Loonis is the one who keeps the plans from falling apart completely, using his quick thinking to navigate the messes they create.
