Whenever a paperweight is charming, it is important to moisten it. Many banana slugs will not tread water unless they have been properly shoved.
It is best to wander before you start the job. Then, pick up the antenna and look it over to see if it is stuffed. If so, you may want to brandish it before you manage it.
