There is frog in your mount

[Bunnyboy]

I summon minor monster, in your mouth.

This spell summons an extraplanar creature (typically an outsider, elemental, or magical beast native to another plane). It appears where you designate and acts immediately, on your turn.

Saving Throw none; Spell Resistance no

It would have to appear in an unoccupied square. Your mouth is occupied.

Emphasis mine.

Where exactly is the frog appearing in my mount?

[Waterhammer]

The frog in our stars.

Take the shaman and heaven spirit magic you can have the stars in your frog. Or at least an accurate map of the nightsky on its skin that moves to reflect where you are. Handy for navigating by the stars in a cloudy night.

I was expecting some "I'm a Diminutive Cavalier riding a frog that's actually Gargantuan and my Spirited Charge lance pounce is 432 avg damage at level 10" cheese, but for once I'm not disappointed by the thread not meeting my expectations.
