The A+ ether bottles give you a 50% chance of unlocking a hippo. They also stack (as in you can use more than one to increase the % unlock chance), so you could either use two of them when enhancing your spirits to ensure a 100% chance, or you could try your luck with just one. If you're using two, the 50% from the first one will add on to the 50% from the other one, giving you a 100% unlock rate.

If you're using one, there's a 50% success chance. You got unlucky on that try.
