How to Clear Gobliiins Level 7
Switch to 
Hooter/Ignatius and change the cursor into a fist and
click the brown bag. This makes the bag move to a safer location.
Then have him walk to the end of the branch
above the patch of tilled earth.
Then switch to 
Dwayne/Oups and change the cursor to an open hand.
Click the brown bag to pick it up. Change the cursor to an arrow and click the
patch of tilled earth to make him stand on it.
Switch to 
Bobo/Asgard and have him punch the scarecrow. This makes
sure that he's in the right position to hit it again.
Then switch to Dwayne/Oups and
change the cursor into a fist. Click the patch of tilled earth to sprinkle the
seeds there, but quickly switch to Bobo/Asgard, and as soon as
the birds appear on the right side of the screen, have him punch the
scarecrow to scare the birds away. Then switch to Hooter/Ignatius
and have him use magic on the cloud above the scarecrow. This will water the
seeds and make the Bald Plant grow from the field.
Switch to Dwayne/Oups and change the cursor to an arrow
and click the Bald Plant to take it. Niak the wizard will appear. Change the
cursor into a fist and click on the wizard.
This completes the level. Make a note of the code in the bottom-left of the screen ( ), then click anywhere to continue to the next level, The Prison.
