I used water weld and created a small ball, I took the skeleton of the frogspawn and squished it into the ball so it would go up the sides a little. I then put the frogspawn back in the tank and let the water weld sit out to dry. Once dry I put superglue in the indentation from the frogspawn and then lined the frogspawn back up with its marks. I then put superglue on the flat bottom of the water weld ball and then stuck it to the overflow. It ended up making it very secure.
