Rapunzel's Naughty Chameleon
Logic · proposed by @lumiere
Pascal, Rapunzel's chameleon, fell down from the 34 feet tower Rapunzel is in! Since the tower has no stairs at all, Pascal has to climb vertically. At day, Pascal can climb a height 4 feet, while at night, it has to sleep, causing it to lose a height of 1 feet with respect to the ground. How many days can Pascal climb back to the tower?
