I have caught every critter from level 1 to level 11 , is there any others I need to be trying to get? Still need to spot one more. Is this a glitch or????

The kangaroo vase needs wildlife from level 11 and up.

If you meant 11 and up, as Tracey said, then it just means you've crossed off one or more off your list that shouldn't have been. I just did that and had to go through just about the whole list again for my hippo vase. I write down the critter i'm hunting and then cross it off as i go but i had the whole list as spotted but needed another one so as i said, i had to pretty much go through the whole lot again and finally got flowers. I had leopard crossed off but i obviously didn't spot one to eliminate it but crossed it off....arghhhh. 

It could also mean that you spotted something in your own garden and discounted it.  It has to be spotted by someone else.

That's true, Tracey, forgot about that. I will say though that for me, it was just the fact i messed it up :)

Yes, I have caught all of level 1 and the next level. I've had a list and marked every critter off. So frustrating.

Ainsley, you need to be hunting in 11 plus....

Unfortunately, you can only do as Lesley suggested.  You've missed something along the way, so you'll need to start again.

I've messed up that way too, more than once :)

Yes I have completed level 1 and level 11 plus. Thanks.

Start fresh with a new list...from giraffe down through the gorilla. As you spot in other gardens, note whether it adds to your vase or not. If you have another vase for level eleven and higher critters in your garden at the same time...you might have to spot the same critter twice if it shows in the vase further left. You can also test by attracting...but the spotting MUST BE DONE by someone else.
