Funky foam makes most wonderful fish (if a little dead, floating on water), when accompanied by a tea strainer, mini fishing net or in this case a spoon? It provides a great fishing activity. I originally did this a responsive activity in pre-school sunday group where I wrote words on one side, with affirming words about what God thought of the, subsequently a memory verse. You could equally do the affirming words with any group of children, even allowing the children to each pass thier fish to a friend. This group of fish had various emotions drawn on to allow discussion about emotions.
This would be a useful activity for any of the fishing stories in the Bible, particularly the Jesus ones, it's easy cheap and fun (and the children could make the fish)
Just be aware little ones might bite fish and funky foam breaks with little teeth so supervise or reconsider with little ones.
