Going to the store

In this comic strip, Pinky and Spiky will buy extra materials to extend their greenhouse.
It looks like they want to accommodate more fruits / vegetables in their greenhouse apartment.

But they have a problem!

Don't worry! Pinky can handle it!
And they managed to cross the lake with ease!

By the way, if you are familiar with the game "GTA" you can understand what Pinky did, because the word "seaways" is a cheat in the game that allows your car to pass a lake/sea/river.
