For certain events, we may ask for a discretionary donation to the Grand Rapids Griffins Youth Foundation. Submitting a Griff Request Form does not guarantee an appearance. Griff appears for approximately one hour per appearance (e.g. If the event runs from 1:00-3:00, he may appear from 1:30-2:30). Participation in outdoor appearances may be cancelled due to inclement weather at anytime - he hates getting wet!
