We cant't think of a witty caption, so we're just going to quote the actual lengthy description from the park website:
Get ready to board the little tugboat that’s got lots of wacky and not a lot of steady.
Hopefully this colorful cartoon ship will stay afloat, but the way things are going, don’t be too sure! It’s a tug boat that not only tugs, it swivels and twists and scoots across the rocky waves. Hang on tight for this fast-paced wobbly twister, perfect for smaller adventurers who are ready to take on some faster moving rides.
The little river boat swiftly slides up and down while it spins around, producing a very wobbly and woozy trip. If your little daredevil can handle some slightly rougher seas, they’ll feel like a seasoned deep-sea fisherman after this wild, unpredictable coast over the wild river waves.
