Break the Click Clock Wood boulder
It is possible to break the boulder blocking the Beaver's hole in Click Clock Wood on the Spring level. Stand on the ledge above the rock, then find the correct angle just to the right of the rock. Drop eggs onto the boulder to break it open. Then, swim into the hole on this level to find some glitches, such as the Beaver still asking you to move the now destroyed rock.
