This is the listing for the water pump activity lid 
 
IMPORTANT : PLEASE NOTE THAT DUE TO SUPPLIER ISSUES YOUR LID WILL NOT NOT BE TINTED BLUE, IT WILL BE EITHER CLEAR, WHITE OR OPAQUE BABY BLUE - IF YOU HAVE A COLOUR YOU REALLY DO NOT WANT TO RECEIVE, PLEASE TELL US IN THE NOTES, THANKS To use, you simply place the pump's rubber tube into the small centre hole of the lid and the pump will rest in the white ring and not slide around.Make sure your tube is submerged in the water, you will need about 2cm of water in the trofast trayThe pump comes with a USB charger and comes with all the info you need regarding how long it lasts etc. You have the option to buy it with or without the water pump I have given you the link below to the exact one that we purchased if you prefer to buy this yourselves We provide it as an option for anyone that may not have amazon prime accounts.

The Large set is the full lid which wraps around the whole of the rim of the large trofast tray and comes with :
one cup (Colour may vary) and a 54mm thick plastic tube and 2 splash shapes which you can sit in the water in your trayThe 'draining' end has 25mm gaps between each slot, so fingers can't get trapped. 
The half set is the lid that sits at one end of your large trofast tray and comes with a tube, one splash shape and cup Please see your options in the drop down menuPlease read the following : 
This is an item intended for supervised play only 
please do not use dyed water or soapy/toothpaste water as this may damage the pump 
the packs of splashes will vary in colour (tinted blue, solid blue or white, or a mix, and will vary in size) 
We recommend you cut your rubber hosing in half when you receive this as the one that comes with the pump is quite long, and half the size is perfect and safer (And gives you a spare)
Your full lid may come with a sacrificial solid activity lid to protect it in transit, so this may be a perfect 3mm solid lid, or a seconds item we have spare. Please find a use for it, or dispose of if necessary
Please don't use the water pump with any MDF or Plywood items as they are not water resistant
The items in the photos are props we have used and are not included in the sets (Only what we have listed above) 
If you are ordering without a pump as you may have your own, please check that the diameter of the base is 73/74mm and if it is different, please let us know in the comments boxFor the Dish washing set, I got this is Quality Save (But I have seen it on amazon, and make sure you buy the one that says hte draining board is 30cm, as this fits the trofast trays perfectly) The Teeth set on Amazon, The blue stones on Amazon 
It is made to fit the large trofast tray (42x30)
