Anaerobic Cycling (無酸素鵠アロバイク Anaerobic Bike) is the fourth stage in Pumping Titanium.
- After 3.3 seconds100f, infinite Squire Rels spawn, delay 13.3~20 seconds400~600f.
- After 10 seconds, 2 Sir Rels spawn, delay 6.7~13.3 seconds200~400f.
- On base hit, Oldhorn spawns as the boss with:
- Infinite Sir Rels, delay 2~8 seconds.
- 3 Li'l Zyclones, delay 26.7 seconds800f.
Li'l Zyclone makes his UL debut here and he's here to make sure your attackers stay in one place while Oldhorn lumbers his way to your base. Thankfully Li'l Zyclone does as much as a loaded squirt gun, so you can use that to your advantage, stacking attackers like candy. Slapstick, Cameraman, and Can Can will be your powerhouses here, with Thaumaturge, Ururun, and Mina as the debuff squad. Feel free to add any offensive Z-Killers if you like.
