Spelling it out

My son spends bathtimes mixing up 'potions'. He keeps them in kinder egg cases special potion capsules and checks on them regularly. The potions themselves are made up of soap, toothpaste, bubble bath, shampoo magic, dragon's urine and chest hairs of an elf.

Every now and again, the potions disappear, when the mixture has become so rank I have to throw it away obviously stolen by a rival sorcerer. The thing is, my tea had a strange taste to it earlier and ribbit....ribbit....ribbit....
