A young lad (Louis Paul) returns home from school, feeds his pet canary a sugar lump then heads to the fair where he takes a shine to a goldfish that's the prize in a roulette competition. He can't afford to play but a man (Gilbert Hugues) comes along afterwards and to the obvious chagrin of the fish, determines he is going to do a bit of spread betting so he can win it at all costs! Amusingly, the fish is having done of this and is steadfastly remaining inside of it's rocky hideaway inside the tank. Failing to convince it to come out, the man must make do with another. Luckily for the youngster, a slight incident with the gent costs him the empty bottle he was carrying, so the man gives him a few Francs and he has a go on the wheel. This time, the fish is much more forthcoming - it practically swims into his net! Now we enter "Tweety Pie" and "Sylvester" territory as he takes it home, only for it to be enthusiastically welcomed by a neighbouring cat. Some fun acrobatics now ensue that sees the fish manage to jump from the bowl and now, lying on the table top is easy pickings for the interloping cat. Will the cat prefer the fish or the now frantically distracting canary that seems to be buying his golden friend time until their friend returns from school? Well? Now we get quite a surprise, the chirpy music picks up pace and the boy gets home from school with a gift for the tank. There's no dialogue, just a gently accompanying score and that works fine for this slightly too long, but engaging quirk of nature.
