\*\*What I expect to happen:\*\*The obstacles should loop.

**What actually happens:** The obstacles disappear when they go off the grid.

**What I’ve tried:** I’ve tried to match the student coding to what the answer key says, but it doesn’t appear to work.

The seagull is moving on the y axis and the student has reset the X location.

This will help the seagull that is moving to the right.

Hi @sanema,

Cool game! As the other user alluded to, I’d recommend looking more closely at which seagull you are changing and which axis (x or y) it’s moving on. Tell the student that & they should be able to problem-solve from there!
