Kobi needs to paint a wall on the estate, but he can't decide which colour to use. Mali, Sam and Bella aren't keen on Kobi's options and are very keen for him not to use the grey from the leftover tin. They search the estate to find a colour to inspire Kobi, but in the end they decide to invent their own brand new colour. Unfortunately, attempts to create a new colour result in a horrible muddy brown mess. However, when Mali accidentally makes a messy paint mark in the kitchen, Bella is inspired to propose that they paint a mural. Show less
