Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
On a rainy day, siblings Sam and Lucy decide to paint pictures in the living room. Sam paints a picture of a blue ocean, while Lucy paints a picture of a green forest. After finishing their paintings, they leave them on the table to dry and go to their rooms. Their mother comes home and accidentally spills water on both paintings, causing the colors to mix and create new shades. When Sam and Lucy return to see their paintings, they don't know what happened. What do they think?

Respond very briefly.

Sam and Lucy might be confused and surprised to see their paintings with colors that they did not paint themselves. They might think that the rain somehow got into the house and affected their paintings, or they could suspect that the paintings were tampered with while they were away. They may not immediately understand that it was an accident caused by their mother spilling water. Without knowing what caused the mixing of colors, they could come up with various guesses, such as the paint not being waterproof or someone playing a prank on them. The unfamiliar shades on their paintings would likely prompt them to ask their mother or each other what could have happened during their absence.
