The Pricklebush is an obstacle seen in a few episodes. In Bananas Without Pyjamas, when B1 and B2 are about to get their pyjamas, they just go through it and get pricked right away. The prickles all end up stuck to the bananas. In Rock-a-bye Bananas, B1 is lying on a hammock right over a Pricklebush and gets pricked, with 3 prickles getting stuck to his pyjama bottoms. B2 ends up having to remove them from B1's pyjamas.
