Wee woo! Wee woo! What an alarming, yet melodic tune, and so classic. What's that you say, Squishable GO! Ambulance? It's not classic? You're trying an entirely new cutting-edge siren sound? Ah yes, now I hear it - regular ambulances say Wee woo! Wee woo! Way to follow your own tune! I feel like both little ditties get the point across, and either one is an improvement on just yelling at people to please move! At 12", Squishable GO! items are the perfect middle size between Big and Mini Squishables!
