Bumblebee cooed as he grabbed the tail, nipping at it when it tried to escape. He didn't acknowledge the creature on the other end, peering down at him to see a playful stranger.
Two more creatures appeared, displaying their red and gold coloring proudly. Both sniffed at the baby curiously but did nothing to stop his little assault on their leader. The winged one gave a screech towards a direction opposing them while the large, bulky horned one lay on all fours before placing his helm beside the happy sparkling.
Pupil-less aqua optics met soft blue and light blue-pupiled ones, making the baby smile at his own reflection within the creature's eye.
The creature whose tail was within his tiny servos moved his helm to meet the sparkling face to face. He growled in approval, pushing the baby's face gently with his snout but froze when Bee grabbed it and held it firmly. The baby then jumped and latched onto his nose, eventually sitting on top of his snout happily.
The baby didn't know what these animal-like mechs were, but he liked them.
The horned one roared upward at his leader, earning a joyful cry from the sparkling seated on said leader. He smiled to himself when the larger one leaned down and pressed his snout against his own, forming a bridge from one to another for the baby. The next response they got was Bee carefully climbing up the horned one's helm.
A laugh emitted from the bulky creature as his tiny servos pawed a ticklish part before jumping off and landing on the large spine. The sparkling shook the sting of the fall and continued to venture down the creature's back, sliding down part of the tail before the animal-like mech swung it around to bring Bee under their observances once more. They knew better that if they let the child out of their sights, the blue, white, and black mech with the powerful hammer would tear them apart piece by piece while they were still alive.
The baby gently was placed on the ground, the largest creature looming over him protectively. Slowly, he walked away towards a stray playground near the city; the creatures trailed behind, carefully trying not to step on him.
Bee giggled as he lay on his stomach and began sliding down a faded blue half tunnel that stretched from the high platform to the ground. The bulky creature was at the bottom, awaiting the little one with infinite patience. He grunted slightly when the baby pounced onto his snout and lay carelessly across it, still laughing and cooing at the experience.
When they heard footsteps behind them, they snarled in defense but the baby smiled, alerting them that whomever it was the sparkling knew. They huffed in relief when they saw it was only the blue, white, and black leader. Carefully, the lead creature picked up Bumblebee with his tail and placed him in the arms of his adoptive sire who then cradled the baby before thanking them and turning to leave.
As the sparkling and the leader left, they noticed the baby had hopped onto the leader's shoulder and was waving at them with a squeak emitting from his vocals. The bulky creature returned a faint smile and raised his own paw to say goodbye to the tyke. The others did the same.
AN: In case you're wondering why I don't refer the the Dinobots by their true names, it's because instead of doing this in multiple perspectives (like I usually do), this is in Bumblebee's and Bumblebee doesn't know what they are nor does he know truly who Ultra Magnus and the others are either other than his caretakers.
