Yes, I think its a good idea.
I know, when we get our new boat soon, I am getting Ethan and Frisk one for each of them.
Mainly because we took Frisk to the river once, and my dad had wadded out in the water to fish, and Frisk went swimming out after dad and got caught up in the current and was being swept down stream. Dad luckily noticed and swam out to save the poor guy. Frisk-man was so tired from fighting the current, that if dad wouldn't have got him, his poor legs would have gotten to tired to keep himself above water.
He is MUCH more supervised at the river now! I had felt so bad for not watching him close enough. Now he doesn't get in the water unless I am there by his side.
