# --description--

_Most_ penguins do not have a square head.

Give the penguin a slightly oval head by setting the radius of the top corners to `70%` and the radius of the bottom corners to `65%`.

# --hints--

You should give `.penguin-head` a `border-radius` of `70% 70% 65% 65%`.

```js
// Maybe check for individual border-radius properties?
assert.equal(new __helpers.CSSHelp(document).getStyle('.penguin-head')?.borderRadius, '70% 70% 65% 65%');
```
