Can the iceburg tip

You tip the iceberg by having more than 30 penguins drilling in one section of the iceberg at the same time. This has happened before, but I don't remember the number of penguins. To be on the safe side, don't, since the water is cold and the EPF will have to rescue you. No point in bringing a bunch of Unknown penguins investigating when all you want to do is get out of the water!

1. You must get the drilling hat
2. There must be at LEAST 30 penguins
3. You all drill

4. The iceberg topples over!!!!!!!!!!!!!!

I really hope that the answer that I provided is helpful to you!
