The players face off against a Titanoboa, one of the largest megafauna of its time.
The Titanoboa starts on the right-hand side of the screen. It attacks by either:
- Head Slam – Rears its head back to telegraph, before slamming it down on players, pushing them away. This attack is aimed at the last player to of damaged the Titanoboa, and only its head pushes.
- Tail Sweep – Its tail appears above it, hovering for two seconds before slamming down in front of the Titanoboa, then drags along 25% of the screen (toward the left side) before removing itself. The tail acts a barrier during this time. It bounces players that it hits.
- Switch – Titanoboa snakes along the ground, its head repelling whilst its back bounces players. Player who dive attack during this time still do damage, and are bounced.
Left, right and bottom of the screen and a small area just above the top of the screen. Whilst the left, right and bottom sides of the play area stop all momentum, the top side flips Y momentum.
The boss is a Titanoboa, the background a swamp land, with mountains visible beyond the trees (Which themselves are beyond the swampland). It is a clear day.
