Lola Went To Beach

We have always want to let Lola try her swimming skill. All the while, searching for a suitable spot for her to swim. Finally we find a quiet beach where we can let her swim freely. When she first arrived at beach, she felt hesitate to step on the seaside, as the sand will be brought away by waves and sink. She moved her head to right, then pause for few seconds, and moved to the left. "eii.... What's this??", I believed this was the question that bothering her.
