This is my final free sketch although this turned into a full blown picture rather than a sketchy type one. This is for my big brother Zeezee. He's so clever. There's a little story to go with this
*******

Gem was in the garden one day playing quietly with grass. She would pull up pawfulls of grass and then let the gentle summer breeze blow the blades from her paws where they would scatter on the wind. gem would giggle happily as she watched the green blades tumble to the ground.
"Watcha doin sis?"
She turned around to see her big brother standing there, his head cocked to one side, a puzzled expression on his face.
"pwayin'" She muttered, grabbing her tail and trying to make it look like it was standing up on it's own. She admired her big brother heaps and she wanted to be just like him, but her tail was still very weak and she didnt have the strength in it to hold it up like zeezee could do.
He watched her for a moment then looked around the garden, he saw something interesting and turned to her, his ears perked up hopefully.
"you wanna play mud monsters?" he asked.
Gem's eyes wandered over to the large puddle of mud in the garden.
"are there monstas in...mud?" She asked suddenly feeling scared, and she gripped her tail tighter wishing she had her toy caterpillar with her but she had left grub inside.
Zeezee shook his head.
"no no, theres no monsters in mud. but we can look like monsters and that would scare any other bad things away" he said knowing he could play on Gem's fears to make her believe pretty much anything he said.
She liked the idea of frightening away any bad monsters and she toddled after Zeezee as he led the way over to the large puddle of mud.
They both looked at the puddle for a moment in silence, both knowing they weren't supposed to get dirty and weren't supposed to play in mud or puddles at least without their wellington boots on.
They stood there for what seemed like hours before Gem made the first move. She bent down and went to scoop up a pawfull of mud, but she was quite an unstable little squirrel and instead ended up falling flat into the puddle. there was a brief moment where the world seemed to stop and gem didn't know whether she was supposed to cry or laugh. Zeezee wasn't sure what she was going to do either and before she could start crying he quickly grabbed a pawful of mud and crammed it onto his head.
"look Gemmy, we're the same" He said standing there in his t-shirt and pullup looking down at his muddy sister sat in the mud puddle
She looked up at him for a second then a large grin spread across her face and she kicked her legs up and down splattering mud onto both of them.
"We're mud monstas!" She squealed happily, giggling at the squidgy feeling of the mud between her paws and on her face. She squelched a pawfull over her brother as he put some in her hair. The two of them laughed and giggled as they covered one another in mud.
"Kids!!! Lunch is ready"
Both of them paused as they heard their mum calling and looked towards their house. They looked at each other and at the mess they had made. Together at the same time the realisation hit them
"Uh-oh" They both mutter. Mum and dad were not going to be happy. This was going to take some explaining.
