Birds Galore
To recieve multiple birds at the same time in a level:

At the BEGINNING of the level, face the opposite direction from which you go (a.k.a wall). Type ''jjbird'' (as in the cheat) multiple times in a row. Every time the bird leaves and comes back, it will bring the previous ones along with it. So, if you type ''jjbird'' 50 times, you would have 25 birds following you.
Note- If you get hurt once, all the birds leave.
