This stage just sucks. The stage will send nothing until you hit it, so stall for as much wallet as you think you’ll need. Once you hit the base, Razorback and Othom will spawn together. Permafreeze Razorback with Bomber immediately and stall Othom perfectly or die. Fun stage design. Use Idi when Razorback is inevitably knocked back before Othom dies. You win when either one dies.
