Rumble and Applebloom aren't happy with theirselves: they're both skinny and physically less mature than everypony else their age, so try an enhancement potion to improve their reedy bodies! The results however, prove to be less desirable than they expected thanks to an accidental mix-up. The powerful enhancement potion works its magic leaving both of them in very awkward scenarios, and things only get steamier over time as they attempt to throw together an antidote to reverse the changes!
