Jacob grinned as he found an option he apparently liked, "Well for this I think we better go out to the garden". Having agreed to this in the first place Matt followed Jacob asking, "Can you at least tell me what it's going to be?". "You'll see soon enough", his friend replied.
Out in the garden Jacob directed Matt to an empty spot, stepped back a bit, aimed and pulled the trigger.
At first nothing seemed to happen, but then Matt gradually, increased in side, "What the fuck? I'm going to be a giant?". Gradually his body became more and more round, with a constant circumfence around his upper body. Gradually his arms started to fuse with his body starting from the armpits and running down until his hand while also becoming much wider. Matt's nose became longer and pointer as his neck disappeared forcing him to look straight up. While this he increased in size, except for his legs which became more and more round and hollow while being far to short for his huge changing body. Suddenly he fell over with a loud thud. "Outch", he exclaimed, and Jacob replied, "Well soon you'll be more pain resistant" having a grin on his face. Matt's stubby legs started to grow one flat protrusion each pointing upwards. His former arms, along with his legs started to form a surface with his tubular body on top and his legs below. Small rods formed downwards lifting the changeling up from the ground. On their ends wheels started to form. On Matt's back part of his body started to form a cockpit, designed for a crew of two, giving good visibility of them. Eventually his face filled up into a pointy aeroplane nose, with his eyes and mouth turning into paint job versions of themselves.
Jacob, the purple bounce ball person climbed on top of the wing and into the cockpit. Being filled with air made this easier. "Hmm, a rubber person might make a good pilot", he pondered" as he bucked up inside the cockpit.
