Below is an old example of Level 380 (I didn't have time to make a new one) Being several years old also explains why they look different.
And here are my tips:
The trick to this level is to keep clearing the 'exit' in the middle of the last board.
Use the line blasters on the left to remove mesh from the right.
The rocket booster built up within the game is also good to use in the middle column, plus in the column just to the right of center to bring the Pets down.
