Octonauts Gup - B

I increased infill on bottom to 25% hoping this will float upright and it does if the top layer is 15% infill. This will still float with a character inside and makes bathtime super fun. Use some clear silicone RTV sealant (Automotive gasket glue)  and a couple of rubber bands to line up the two halves, wait a couple of hours to dry. If you push the character's hands down into the cockpit the character will be wedged into position for some fun deep-sea diving and soap bar rescuing.
