Whew! I still haven't unlocked the last universe! I know that the short cut is that you go through the Delta wormhole, then through the Alpha world, go to Necrox, and visit the old man at the shop, where we will give you a time challenge!
The next one will be "Robot Wants Birdie" or Robot Wants Hamster", or maybe Robot Wants REVENGE!". And there will be stations where you can combo with the two, and puppy will chase kitty and blow enemies skyward and puppy can scare kitty while robot is on kitty and he can launch. I want to fight that unborn guy with that tentacle thing.
