A B.B.Bunny with bigger ears, bigger range, and a slightly bigger money drop. At 200% strength magnification, it has 130k HP and about 12.5k DPS, which is delivered through two consecutive hits that deal 9k damage each. Interestingly enough, the second hit also adds 100 piercing range, meaning units with under 150 range will suffer double damage. With their piercing range and 30% chance to knockback cats, groups of J.J. Jackrabbits can push at an alarming rate.
Was about to be used in a genome experiment in the Laboratory of Relics. However, it escaped in place of Sir Seal. Every company it ran went bankrupt during its absence, so it's started a new business telling fortunes with the crystal on its rear.
J.J. Jackrabbit's Japanese name, Ōusagin, is a combination of ō (big), usagi (rabbit) and gin (money).
According to its Japanese description, B.B.Bunny was set to become the first RedColossus but switched places with Sir Seal partway through, leading to an incomplete J.J. Jackrabbit and the creation of Baron Seal.
