Journeys: Kidneys. Stop 4
Colour clue
The colour of wee tells you whether you drink enough. Throw a dark tube to Growney with a glass, and a light one to Growney running!
Yes! The colour shows whether you need a drink.
Look closely! Dark wee asks for water, and pale yellow says all is well.
The tubes are falling faster! Don't drop any.
Pale yellow wee says you drink enough. Dark wee says it is time for some water. And that solves the whole mystery!
