"We were watching the otters play when they started mimicking my son," the uploader wrote.
The boy's sister watches the scene in the video and determines she will also get the attention of the otters if she dons a Snoopy hat like her brother's, but the mammals do not show interest in her.
"My daughter thought if she put her snoopy hat on the otters would follow her also but once she put the hat on they ran away and she pouted," the mother wrote.
