Bark your way out of here.
Branch out and try something new.
Don't be a sap, make a change.
Get your bark on and make a move.
Don't be a stick in the mud, branch out.
Don't just sit there, leaf.
Don't get stuck in the trunk, branch out.
Don't be a tree-t, get moving.
Don't be a tree-mendous bore, do something different.
